Why not stretch another wire above the electrified one and take it directly to ground so that if the antenna wire does contact the fence wire it will short to ground as it will likely be on the upper
Thank you all for taking time to respond. I think I'll incorporate a couple of suggestions. It looks like a properly installed commercial arrestor alone should provide the protection I need. In addit
If you take W5DXP's suggestion to make a folded dipole out of ladder line, you can purchase copper clad steel ladder line... then you've got good insulation, the strength of copperweld, and an anten
Yes, thank you guys for this info. I wasn't even aware copper clad steel ladder line was an option. I've been looking a ladder line based dipoles today and I think this is the way I'll go. It took me
Just remember that the folded dipole has about 300 ohms impedance at resonance and needs to be fed with ladder line or a 6:1 balun. Jim Rhodes K0XU jim@rhodesend.net Experience is the thing you have

Sheesh Why not just put the antenna up so it will most probably NOT come down so all those around here will stop playing chicken little.... A little over-engineering will go a long way. And then if i
Roger- How DARE you point out the obvious solution? I read a couple of the posts on this thread- decided it was obvious and trivial- Then deleted MANY, and accidently looked at this one. Sheesh, inde
Using insulated wire is certainly an option. This is the first HF antenna I've put up so I'm just beginning to explore what is available in terms of materials. The use of insulated wire begs a couple
My first reaction to this problem was to think about insulated wire. But generally, the insulation is rated to 600V. Won't cut it, for a HV critter fence. On the other hand...put a DC block at the se
ORIGINAL MESSAGE: -- REPLY FOLLOWS -- Be careful with a "DC block". If the antenna first touches the energized wire during a peak of the cycle, a 5kv pulse will occur and will be definitely be couple
JeffWhen I commented on Rogers post, I did NOT mean the problem, or his answer were trivial- Far from it. I was referring to some of the answers that came earlier. Your problem is very real. Two aspe
