THIS YEAR WE TRIED SOMETHING DIFFERENT. WE SETUP SHOP IN THE BUILDING WITH ALL THE MAJOR VENDORS. AFTER EVERYONE FIGURES OUT THAT WE HAD CHANGE OUR NORMAL LOCATION (OUT IN THE TAILGATE SECTION), WE WERE ONCE AGAIN A COMPLETE SUCCESS!!! ON OUR NINTH PUBLIC OUTING, WE WERE COMPLETELY SOLD OUT OF ANTENNAS AND ACCESSORIES BEFORE LUNCH ONCE AGAIN. WE WERE THEN ABLE TO TALK TO THE MANY HAMS THAT EXPRESSED INTEREST IN THE D&G LINE OF PRODUCTS. A FEW FORMER CUSTOMERS STOPPED IN AND LET US KNOW HOW THE PRODUCT THEY PURCHASED WAS HOLDING UP UNDER ACTUAL WORKING CONDITIONS. ALOT OF GOOD FIELD DATA WAS COLLECTED ONCE AGAIN AND WILL BE EVALUATED BY OUR R&D DEPARTMENT. NO DOUBT THERE WILL BE A FEW MORE PRODUCT IMPROVEMENTS AS A RESULT OF THIS CUSTOMER FEEDBACK. WE NOW TAKE THIS OPPORTUNITY TO THANK ONE AND ALL FOR MAKING OUR NINTH YEAR IN THE ANTENNA BUSINESS A SMASHING SUCCESS! WITHOUT YOU GUYS OUT THERE NONE OF THIS WOULD BE POSSIBLE. AFTER ALL THE SHOP TALK WAS OVER AND ALL THE BUSINESS WAS CLOSED UP ,IT WAS THEN TIME TO BE JUST ONE ON THE GUYS AND SEE WHAT GOOD DEALS WE COULD FIND OUT THERE! THIS YEAR WAS BETTER THAN EVER. THANKS AGAIN.

HALF WAVE END FED ZEPP ANTENNA
(Made to Order)
This Classic Antenna Consists Of A 125 Foot End Fed Flat Top Wire With 50 Feet Of Parallel Feed Line. Excellent Antenna For Places Where A Centered Fed Dipole Is Not Practical. This Antenna Can Also Be Used With A Conventional "T" antenna Tuner. No Special Equipment To Purchase Or Construct. Just Put Up, Hook It Up To Your Parallel Output Of your Current Antenna Tuner And Begin Working Your Friends On The Band! For those who do not have space to erect a full size Zepp, we offer a half size version that also tunes 80-10 meters. Just 66 feet in length and 30 feet of 300 ohm ladder line to a tuner will give a respectable signal out on all the amateur bands 40-10 meters.
This All Band Antenna Consists Of 125 Foot Dipole Configured, Flat Top Fed With 50 Feet of 300 ohm Parallel Feed Line. Another Time Proven Design Which Will Prove To Be a Great Performer!
A Multiband Antenna That Enjoyed Considerable Popularity in The 1930's was Named for the Amateur Who Wrote a Comprehensive Article About It. The Antenna Consists Of A Half Wave Length Antenna on the Lowest Frequencey to Used, With a "Single Wire Feeder" Connected Off Center. The Antenna will Operate on the even Harmonic Frequencies, and Thus the Single Antenna Can be made to Serve on The 80-10 Meters Bands. The Single Wire Feeder Shows an Impedence of Approximately 600 Ohms to Ground, and Since The The Return is Through The Earth, a "Good Ground Connection" is Important to The Effective Operation of This Antenna. The Second Requirement is an External Antenna Tuner to match The SWR to The 50 ohm Output Of the Modern Transceivers. We Offer another Model of the off center fed antenna which Uses 300 ohm 1KW Rated Ladder line Instead of a Single Wire Feedline Attached To The Balanced Output Of The Antenna Tuner. This antenna is Configured Exactly the same as Our Other Model Just a Different Feed System and The Neccessity For "good" Ground system" Is Not High On The List of Required Elements To make The Antenna Work well. Either Antenna Is A good Choice For Multiband Operation. You Should Be Pleasantly SSurprised At Just How Well This Antenna works.
We Use 102 Feet Of #14 Stranded Wire For the Flat Top And "Are Proud To Announce The Upgrade To A 30 Foot Section Of 300 Ohm 1kw Ladder Line" For The Tuning Stub. No BALUN Is Used As A BALUN Dramatically Reduces All Band Operation And Transmit Efficiency. This Very Popular Antenna Has A Broadside Bidirectional Low Angle Radiation (DX) Pattern If Mounted 1/2 Wavelength Off Of Ground At Lowest Operating Frequency, A Higher Angle (RAG CHEW AND SOME DX) If Mounted 1/4 Wavelength Off Of Ground, A High Angle Cloud Warmer (RAG CHEW) If Mounted Less Then 1/4 Wavelength Off Of The Ground. For Those Amateurs Who Have Limited Space And Still What To Get On The Some Of The Lower Frequency Bands A Half Size Junior Model Is Now Available. Made To The Same High Standards As The Full Size G5RV Except That The Total Size Of The Flat-top Portion Is Only 52ft!! Great For A Small City Lot In "1/4 Acreville".
We Also Stock The 160 meter Version Of This Antenna Which Has a 204 ft Flat-Top Portion. This Antenna Like All The Larger Antenna's Are Made To Order And Are Shipped Very Soon After Payment Is Recieved.

"Joe, Thank you for the quick response. My friend Dennis (WH6QN) bought one from you a few weeks ago and we have been testing it out. Your Antenna is a winner !!! We have had QSO's all over the world. Unbelievable !!! As you probably know, in Hawaii, we are forced to do all our Dxing portable (Antenna restrictions), and your G5RV Junior is just the right size, easy to set up, and very effective. Thank you again !! 73's and Aloha !!! Joe(NH7WL)"
THIS IS WHAT BARRETT IN KEY WEST FLORIDA HAS TO SAY ABOUT THE DG-G5RV-AB 40/10
"Hello, Just thought you would like to know that I have strung the G5RV, Jr. up
in the palm trees at about 25 to 30 feet up and it works like a champ.
With the Icom 706 MK IIG and the AT-120 tuner I measure SWR of 1.2 and
1.3 on 40 meters and 20 meters. I have spoken to Belfast, Northern
Ireland; Northern Italy; and Costa Rica, thus far. Many "local"
contacts also. I have everything set up so I can roll everything up and
put it in a plastic box and be ready to hit the road. Your antenna is
very satisfactory. Thanks so much.

THIS IS WHAT TOM IN LAKELAND FLORIDA HAS TO SAY ABOUT THE DG-G5RV-6 METERS
Recently I purchased a K4TR D&G Antenna MFG. & Sales 3/2 waves G5RV doublet for 6 meters. I had been using a 1/2 wave dipole but the performance was pretty dismal. When the antenna arrived I could see immediately that it was built like a tank and would hold up well under most high wind conditions.
I mounted the antenna at 35 feet above ground in a broadside north-south fed configuration and fed with 55 feet of 50 ohm hard line. The performance difference was immediately obvious with signal reports on transmit and receive 59 or better versus 44 to 55 with the dipole.

THE ORIGINAL "W5GI MYSTERY ANTENNA TM"
The W5GI Multi-Band 80-6m Mystery Antenna
A multi-band wire antenna that performs exceptionally well even though it confounds antenna modeling software...
The design of the Mystery antenna was inspired by an article written by James E. Taylor, W2OZH, in which he described a low profile collinear coaxial array. This antenna covers 80 to 6 meters with low feed point impedance and will work with most radios, with or without an antenna tuner. It is approximately 100 feet long, can handle the legal limit. It’s similar to a G5RV but a much better performer especially on 20 meters.
The W5GI Mystery antenna, erected at various heights and configurations, is currently being used by thousands of amateurs throughout the world. Feedback from users indicates that the antenna has met or exceeded all performance criteria. The “mystery” part of the antenna comes from the fact that it is difficult, if not impossible, to model and explain why the antenna works as well as it does. The antenna is especially well suited to hams who are unable to erect towers and rotating arrays. All that's needed is two vertical supports (trees work well) about 130 feet apart to permit installation of wire antennas at about 25 feet above ground.
The W5GI Multi-band Mystery Antenna is a fundamentally a collinear antenna comprising three half waves in-phase on 20 meters with a half-wave 20 meter line transformer. It may sound and looks like a G5RV but it is a substantially different antenna on 20 meters. Louis Varney’s antenna, although three half waves long, was an out-of-phase aerial. Mr. Varney had two specific reasons for selecting a 3 half waves on 20... he wanted a four-lobe radiation pattern, at least unity gain and a low feed point impedance. The Mystery Antenna, on the other hand, presents a six-lobe pattern on 20 meters, gain broadside to the antenna, and also low feed point impedance to simplify matching the antenna to the rig. Additionally, the Mystery antenna is designed to work at least as well, on the other HF bands as a G5RV. In short, the Mystery antenna is a sky wire that incorporates the advantages of a 3 element collinear and the G5RV antenna. In its standard configuration, a collinear antenna uses phase reversing stubs added at the ends of a center fed dipole. These stubs put the instantaneous RF current in the end elements in phase with that in the center element.

FULL WAVE LOOP
This made to order classic antenna is a superb performer. I can be constructed as a single band antenna fed with coax or a multiband antenna feed with kilowatt ladder line. Either configuration would be a great addition to your "antenna farm". Feedback from some of my customer report that this antenna has an extremley low noise pick up on the lower frequencies ande is excellent performer on the upper frequencies for Dx. The choice is yours. Either the multiband version or the single band version would be a great choice.

VERTICAL ANTENNAS
160 METER VERTICAL "T" ANTENNA (MADE TO ORDER)
This Antenna Is Taken From A Time Proven Design. Constructed From durable,UV Resistant Parallel Feed Line(300 Ohm) And #14 Double Coated Stranded,Insulated COPPER Wire, This Antenna Performs Extremely Well On 160 Meters Because Of its Low Angle Of Radiation. This Is An Excellent Dx Antenna! You have the optional to place a matching device at the end of the 300 ohm line(the base of the antenna) or simply use the tuner in the shack which should be sufficient for matching the coax to the antenna. An interesting note is it will Not be Necessary To Have An Extensive Wire Radial System Under The Antenna. The more the better however. As few as 4-10 1/4 Wave Radials Should Be Sufficient To Make The Antenna Really "Sing"!!!! With my modest Modest Wire Counterpoise (12 1/8th Wave Wire Radials) I Have Observed That This Antenna Is As Reliable For DX Work As My 5/16ths Wave "L", And Appears To Be 3 to 4 S Units Quieter Than The "L". This Would Probably Be an Asset In An Urban Setting. Less Noise Pick Up. This Antenna Will Do A Good Job On the The 160 Meter Band.
Another more conventional Configuration Of This Antenna Consists of #14 stranded,insulated copper wire constructed to the same specifications as the balanced feedline version. The advantage of this model is that it is not necessary to have a tuning or matching device at the base of the antenna. Matching can be accomplished by either of the previously mentioned methods. It can be easily fed with 50 ohm coax at the base of the antenna as the impedence is about 30 ohms. The mismatch can easily increased to around 50 ohms by adding a radial system or counterpoise under the antenna and then matched by a tuner in the shack.
160-10 METER DOUBLET/VERTICAL "T" ANTENNA (MADE TO ORDER)
Standard Doublet/Vertical "T" with Switch Box
Multi Wire Vertical "T"
I am happy to announce the introduction of a brand new antenna to the D&G line of antennas. The "All-band 160-10 meter Doublet/Verical "T" antenna". This antenna has been field test by myself as well as KN4LF with great results. The focus was to construct an antenna which would work on all bands reasonably well, and would fill the need of amateur operators to have "TWO" antennas(switchable from the shack) for 160 meters. One Horizontally polarized for distances up 1000 miles(local rag chewing) and one vertically polarized with a low Take Off angle to work DX in excess of the 1000 mile mark. After more than year in the development stage and exhaustive field testing, the antenna has arrived that will fill all of these requirements. If you are looking for a really versitile antenna and have the space to put up a 60 to 70 foot vertical radiator, this is the antenna for you.
The short technical description of the antenna is that antenna functions as a vertically polarized top loaded "T" when the shack activated relay is engaged and loaded up against a modest radial field (I use 36 1/8 wave radials). Deactivated the antenna becomes a horizontally polarized ladder line fed doublet for use on 160-10 meters. This is a very valuable tool, particularly on the 160 meter band. To date my log is full of contacts with Europe on SSB as well as CW, Australia,South America and Oceania, the Ural and Caspian Sea area of Russia and finally the Middle East (Turkey,Isreal and Cyprus). The antenna is constructed of the finest double coated UV resistant #14 stranded copper wire, heavy duty 300 ohm UV resistant ladder line, the KK4TR Center insulator & Coax to Ladder Line connector, high quility coax connectors, relays, sockets, Zinc coated hardware and enclosures. The clickable link below will give you an idea of how the antenna functions. The switching unit is available seperatly and can be ordered below. Any other questions should be directed to to my email address listed at the beginning of this website. This is the antenna you all have been waiting for!! Get on the 160 meter band and have a really competative signal with all those so called "big guns"without the need for a high power linear in many cases!!!!! Don't let this band be a mystery any longer !!!!! Find out what you have been missing all your amateur career!! Come join us on the Band and get a multi band antenna as well all in one really neat affordable package.
As all the fine D&G products, this antenna comes with a 1 yr warantee for workmanship any other damage will be evaluated on a case by case basis.

160/80 METER INVERTED "L" ANTENNA (MADE TO ORDER)
Great way to get on the 160 meter band (or 80 meters) and start working the Dx. This classic antenna consists of a 1/4 wave(130 feet) length radiator and is connected to radials laid out on the ground or even buried under the ground. The radials can either be 1/4 wave length long or as short as an 1/8th wave length long. both will work well. This antenna is the easiest and most convenient way to discover the mysteries of the 160 meter band! I have have used this type of antenna in the past and found it to be a very good performer both locally and with dx contacts as well. Come join in on the fun on the 160 meters or even 80 meters!
"See what Chuck Say's about this 160m Inverted "L" - Hi Joe:
I purchased one of these from you in the fall. I have to say I did not expect to be impressed by 130 feet of wire, but boy, what fine materials and workmanship! I was very pleasantly surprised. Nice, thick wire, does not unravel and make a mess or break like wire used by the others!
I have the apex at 50 feet and dog tailed the horizontal section because of some interaction with one of my zepps. The horizontal section ends at about 40 to 45 feet above the ground.
I used several copper ground rods, a fence post, a tie in to a 300 pound piece of iron that is sitting in the ground field, about 25 1/8 wave radials (I used 4 pair telephone wire, two pair speaker wire - from what I read, wire gauge is not too important, but protection against breakage is), as well as about 75 to 100 square feet of chicken wire - all of this over wet lands. not quite a swamp, but really, really wet.
I work CW only - the SWR at 1800 is 1 to 1.2 - At 1840 - 1860 it drops to 1 to 1 - I can tune the entire 160 meter band with this antenna - the SWR does not exceed 2 until 1900...how's that?
If we have a good rain the SWR at 1800 is 1 to 1.
I would encourage all others who are worried that 100 watts and a simple inverted L with a small lot will not do much - they will do fine; I am working all sorts of DX on 160 - KH6 is the best yet (QTH is NW NJ). Would suggest not to rush the ground/radial installation - I did run the wires on top of the ground, but took care to pound all pipes and posts in as deep as I could and to use first class connectors and solder joints to tie everything together.
Anyway, next time I need an antenna, you have my business. Thanks for 160 after 40 years!

3 WIRE "BOBTAIL CURTAIN" VERTICAL ANTENNA
(MADE TO ORDER)
The Bobtail Curtain is an excellent low angle radiator having broadside bidrectional characteristics. This antenna system uses the principle of co-phased verticals to produce the above mentioned pattern and provides (depending on who's book you read) 5/6db of gain over a dipole. The antenna performs as three phased top loaded verticals a quarter length wave high and spaced a half wave length apart. It is most effective for low angle signals and makes an excellent long-distance antenna for either 3.5 or 7 mhz. In order to have this antenna work to it's maximum an antenna tuner is a must at the feed point of the center vertical element. If this does not present a problem and if you have the space this is the primier DX antenna for 40 and 75 meters!!!!!!! We are not limited to only 40/75 meter versions of this antenna. We now offer a complete line of Bobtail Curtain antennas 80 through 10 meters as well. We now offer another configuration that is fed in the upper corner with 50 ohm coax. The advantage of this arrangement is the user does not not need a parrelel tuner at the base of the center element. The coax is then run to a standard tuner inside the shack. The need for an extensive radial field is no longer manditory. A standard ground connection shack is all that is necessary. I have to add that I have not tried this configuration and have no first hand knowledge about how well it works, but feedback from a recent customer tells how this configuration worked very well for him. Additionally this configuration models out quite well with the EZNEC computer program, so there should be no problem with the antenna. Either configuration is a great choice for a "Kick ass Low Frequency DX Antenna" . I have included two diagrams via the links below for a visual idea of the two configurations.
THIS IS WHAT JOHN WN4OAA HAS TO SAY ABOUT THE CORNER FED VERSION OF BOBTAIL CURTAIN:
"THE BOBTAIL CURTAIN ANTENNA is absolutely the best antenna I have ever had in 37 years. I am using the cornerfeed method on a 30m bobtail with the tails touching the ground, AND the gain is astonishing---an eyebrow raiser. The low takeoff angle allows me to hear and work DX generally an hour earlier than most hams (which means less competition). With 100 Watts I can work anything I hear, even busting pileups --- Europe, South Pacific, Tahiti, and more. Even dropping the power down to 500 milliwatts I can work Europe and DX. If you could only have one antenna, this would be IT! If you have the space for a full wave dipole, then you have the space for a bobtail. A real plus over a yagi due to its low visibility, not an eyesore, and 6db gain in two directions! ! 73 John WN4OAA "
Gain 3.1-3.75 db Over Single Vertical With A Low Angle (21 Deg DX) Broadside Bidirectional Radiation Pattern If Mounted 1/4 Wavelength Off Of Ground. A great QRP Antenna!!!
OUR 40 METER HALFSQUARE PHASED ARRAY READY FOR PACKAGING
KK4TR 160 METER "UMBRELLA" ANTENNA (MADE TO ORDER)
This Antenna Is Taken From Another Time Proven Design. Constructed From durable,UV Resistant #14 Double Coated Stranded,Isulated COPPER Wire, This Antenna Performs Extremely Well On 160 Meters Because Of its Low Angle Of Radiation (Computed At 24 deg TO Angle According to the EZNEC 3 Computer Program). With The Radiation Resistance in Excess of 50 Ohms, This Is An Excellent Dx Antenna! It Will Be Necessary To Have A Tuning Device To Tune The Antenna To The Lowest Swr, Either At The Base Of The Antenna Or In The Shack. A Plus However Is That It Is Not Necessary To Have An Extensive Wire Radial System Under The Antenna. 4-10 1/4 Wave Radials (not supplied) Should Be Sufficient ( Although the more the merrier!) To Make The Antenna Really "Sing"!!!! The Antenna Is Configured With a 65 Foot Vertical Radiator With 3 65 Foot Diagonal Wires Spaced 120 deg Apart. KN4LF Indicates The "Umbrella" Is a Real "Kick Ass" Antenna on 160 Meters. If You Have A spot 60 To 70 Feet Tall This is Definately The Antenna For You!!

KK4TR 5/16th WAVE WIRE "L" ANTENNA
(MADE TO ORDER)
This Antenna Is A Solid Performer On DX And Ragchewing. It Has A High Radiation Resistance And Therefore Is Very Efficient. It Can Be Tuned With Either A Parallel Network Or A Conventional "T" Network Antenna Tuner. It Can Be Installed On A Typical 1/4 Acre Suburban Lot.
Using my 165 foot 160 meter 5/16th wave "L" antenna with a vertical section of 57 feet and 4 elevated counterpoise wires at 15 feet and 8 ground mounted radials, I've worked 50 countries on 160 meters in the past two DX seasons with only 100 watts the majority of the time and occasionally using my Dentron Clipperton "L" amplifier at the 800 watt level. Better then 50% of my contacts were via SSB. Some contact examples:VE1ZZ Nova Scotia, Canada (100 watts) 59 1540 miles, NP4A Ponce, P.R. 59++, 58 with 100 watts 1200+ miles, DJ7AA Germany (800 watts) 599 4900+ miles, I4AVG Italy (800 watts) 59 4900+ miles, VK6HD & VK6VZ Western Australia (100 & 800 watts) 599 11300+ miles,Hawaii KH7R & NH7A (100 watts) 599 6000+ miles,Galapogos Island HC8N (CW & SSB) 59 4000+ miles, FO0AAA Clipperton Island (SSB & CW) 59 4000+ miles,CN8WW Morrocco(100 watts & 800 watts SSB & CW) 59 2000+miles.
