The Quad-County Amateur Radio Club

      With the risk, that you might say, I can’t do that, I say YES YOU CAN!

The other day, I was looking around for a cheap and simple antenna for my brother in-law.  You see, he was asking me if it’s hard to get a amateur radio license, and if the equipment is expensive, so I told him that he could borrow a radio and coax from me, but, I didn’t have any antenna that he could use. 

That’s when I got to think about a neighbor of mine, a few years ago, he asked me if I wanted an old CB antenna that had been laying outside for the last 20-25 years, and at the time, I had what I needed, so I said no thank you, but now it might be a good idea to ask him, and guess what, it was still laying out there, he said, all he used it for was to knock down hornets nests. So I got the “antenna” for free, took it all apart, cleaned it up, and put it together again.

From what I could figure out, it was 11′ tall, and once it did have 3 ground plane-rods. Further more, it also had a coil of some sorts, connecting the center of the PL connector  with the 11′ radiator, and since I had no clue of size, or number of turns, I started to look on the net for a similar antenna, but it was still just guesswork. As you can see, on the picture at the right, I used what I had sitting around, so its about 1 1/2 turns. Then of coarse I didn’t know how long the ground-plane-rods originally were, so I came up with a “one of a kind” solution. Since I didn’t have any aluminum pipes that would fit, I went another route, if you look close, I put “inserts” into the 3/4″ holes, then 3 pieces of 6′ fiber-glass rods were inserted, and on the rods, I wound about 7′ 22 gauge insulated copper-wire. The fiber-glass rods can be found at Lowe’s, they are used as “driveway” markers. I used electrical tape, to hold the wires in place, but shrink-tubes would be nicer.

Now too the fun part, would this contraption work??  As I said earlier, this was an old CB antenna once upon a time, but what is it now?? I hooked up my trusty TS-440 sat, it has its own antenna-tuner, so I tuned in 28,500 and hit tune, well it showed SWR about 1-1:3, so I moved down to 28,020 and low and behold, it showed SWR 1-1:2! Well I thought, just because it shows low SWR, it doesn’t have to be a good antenna, so I tuned over the 10m band, and heard a station in El Paso Tx I had worked before, he was about S 5-5, so I called him, and he did answer, and gave me a solid S 5-9!! This told me that it was not just a pile of junk sitting on my back porch, so then I tried to tune it on 12m, and there it showed about SWR 1-1:3, which is not to bad!! This antenna turned out to work all bands, except 17m, and I guess 160m!! Not to bad of a pile of scrap!!

So now, I’m asking all of you, go out and “save” old CB antennas, give them a second chance, and put them to work on our HAM-bands! When you are done, tell us how good it works, and how you managed to save it from the “scrapyard” Good luck, and hope to see your article here soon!
