ALL CONTESTS & ALL CONTACTS UPLOADED TO LOTW AND eQSL

First licensed in May 2008 as a technician. Upgraded to General in February of 2010.

I use an old ADI AR-147 for 2 meters and an ADI AR-447 for 70 cm. I use them mostly for those local simplex rag chews on 145.7 and 446.0. Bought both of them from a local ham. They look absolutely identical and have exactly the same features on each. I use a Comet GP-9 as an antenna for both through a duplexer.

For hf, I usea Yaesu FT450AT with an A-99 vertical antenna for 10 meters and an end fed wire for 20 and 40 meters.I built a 20/40 meter wire antenna out of 450 ohm window line, but have yet to put it up.

9-28-10 UPDATE

I put the antenna up in an inverted V with the apex up at about 40 feet. I have not cut it to tune it. It is still 33.5 feet on each side. Seems to work pretty good on 40 and 20 meters. If you've talked to me recently on20 or 40, it is with that antenna. I'm kinda scared to cut itnow since it works. I do have to use an antenna tuner though.

01-16-11 UPDATE

The antenna has been cut to 31'6" per side on the 40 meter side and 16'6" per side on the 20 meter side. An antenna analyser was connected to the antenna and it was resonant at 7.025 on 40 meters and 14.254 on 20 meters. I am very happy with the antenna and have worked France, Japan, and many South American countries with it.

03-23-11 UPDATE

Purchased a Yaesu FT857D the end of January. I took it out of the box once when I received it and put it back in the box. I need to get it out and learn to use it. I plan on using it in the June (2011) VHF contest as a rover. I better hurry!

A small lot 80 meter wire antenna

If you think your lot is too small for an 80 meter wire antenna, you have to try this version of an 80 meter inverted vee wire antenna.
It all started about 5 months ago when it was suggested that I get on the 80 meter band. Benny, KW6N, was going to go to Yuma for a week or two in the Winter and 80 meters was the band to contact him on while he was there. He provided my with 124 feet of #14 insulated solid wire, 62 feet of red and 62 feet of black. Well, he went and I had no 80 meter antenna. I did use my 40/20 window line antenna to contact him on 80. It shouldn’t have worked, but it did……but just barely.
I knew I didn’t have enough space to put up a 124 foot flat top dipole. So I went into the “thinking” mode. How about an inverted vee? Nope, can’t get it high enough to accommodate the spread. OK, so how about if I just shorten it and just go as far as I could? Nah, it goes against the “rules”….wave won’t fit….too long for the short wire. OK, so how about a coil of wire like Jim, WA6NIF, used on the end of each leg of his 80 meter dipole and then put it up in an inverted vee?
Well, I brought it up the topic on 145.7MHz and it was suggested by John, K6MI, that the coil of wire be in the middle of each leg of the inverted vee. Hmmm, could this work? I was told to just try it and you will find out.
I went to work measuring just how long each leg could be. I wanted the maximum length of wire without a coil. Well that happened to be about 45 feet on each side of the dipole in a 90 degree inverted vee.
Because I wanted the antenna to be resonant at about 3.80MHz (the lowest I can be in the General portion of the phone band), I used the formula of 468/3.8 minus 5% for a total length of 117 feet or 58.5 feet on each leg. I had two 62 foot lengths of wire. I had it made! Plenty of wire! I remember everyone telling me to keep it long and cut it later after you try it or put an analyzer on it.
From the center insulator, I came down 21 feet and then wrapped 20 feet around a piece of 1½” thin wall PVC tubing used for vacuum systems in houses. Then came down another 21 feet and attached it to an egg insulator and then to the wooden fence along the side of the house (see diagram).
Time to get out the antenna analyzer and see where it is resonant. In my mind I knew it would be too long. So, I attached the analyzer to the RG8X coax and it was TOO SHORT. Resonant at 4.2mHz. Too short, it couldn’t be.
Well, come to find out that the coil in the middle did something. I’m still not sure exactly what. I added 6 feet of wire (just hanging down from the ends) to each end and now it was too long! Resonant at 3.77 mHz. So, 2 feet was folded over itself and it is resonant at 3.82MHz. Perfect!
So, how does it work? Well for a wire it works GREAT. I’ve used it and compared signals with other hams and it seems to be better or as good as what they have. If you hear me on 80 meters, it will be with this antenna!
A BIG THANKS to Benny (KW6N), John (K6MI), and Jack (AC6LT) for all the help and encouragement they provided in making this simple inverted vee 80 meter antenna. I couldn’t have done it without them.
