In my recent post, More from Dayton 2012, I reported on the horse fence antennas made by KF4BWG, mentioning that every time I see them, I get the idea to try and make my own. Well, yesterday, I went down to Tractor Supply and bought 500-ft. of 2-in. PolyTape fencing material and some clamps. I even got lucky and got the tape on sale. Instead of $64.99, it was on sale for $54.99.
This evening, I started playing around with it. The first thing I did was to clamp the tape with the clamps I bought. What I discovered is that the clamps really don’t make contact with all the conductors. They tend to bow, and some of the conductors in the center of the tape were open.
To get around that, I used an X-Acto knife to separate the conductors from the tape and bend them back so that they lay on top of the tape. Now, when I tighten down the clamp, I get a good connection on all conductors.
The problem I’m having now is how to connect the Hy-Q dipole center insulator that I have to the tape. What I need is some kind of clamp that will connect the solid copper wire coming out of the center insulator to the tape clamp. Anyone have any ideas? I can see drilling a hole in the tape clamp to secure the copper wire. Not only would that connect the tape to the center insulator, it would take out the bow in that clamp and make an even better connection to the conductors in the polytape.
