Darwinian natural selection is thwarted in many instances these days as society moves to protect those who would be eliminated if left to their own devices. This is not a good thing for the long term
Amen Jim, Amen! Measuring the RF power at the antenna feedpoint can INDEED be a rude and abrupt bubble buster! What matters then is what if anything is done about it and aye, there's the rub. Patrick
There are paints that don't need primers to go on over rust (just remove heavy flaky rust not light rust.) Rustoleum is one brand with such products. I have used a lot of their "Hammertone" paint mad
I have never personally attached a connector to hardline coax and would like recommendations for connectors, source(s) for same, crimping tool(s) needed and a good source for those. I'd like suggesti

Jeff, It is Andrew Heliax LDF4-50A 1/2 inch. Thanks so much for your generous offer. I am in a rural area and it is 30 miles to nearest technology store and that is a telephone boutique named Radio S
Might not the rotor control cable act as an antenna and pick up RF in the near field of the transmitting antenna? Depending on the extant conditions might this not be enough to cause some problem? Pr

Most all tower users have fairly extensive coax runs on which we depend for near trouble free service. Here is one strange tale... I had been having fits chasing an antenna/feedline/connector problem

The problem was in a 6 ft jumper of RG-58U. I cut it in half and then started to cut off an inch at a time to look for defect. Lucked out and spotted it immediately. The center conductor was migrated

While true, Mark, I isolated the problem to the bad jumper in a couple minutes, as fast or maybe faster than getting out the boat anchor HP to do the TDR bit. I did waste some time comparing good to

My problem coax jumper was solit not foam and it was only bad for a couple inches. I cut some up to check. Patrick NJ5G On 12/16/2014 9:07 AM, K7LXC-- via TowerTalk wrote: I saw some coax a few years

Do not place the rebar directly on the dirt. Use "chairs" or other means to maintain a space. Chairs are little blocks of concrete with embedded wire to facilitate tying. Available at big box stores.

Sorry, I don't get it. If it is a srewdriver thingy then I like the inverted "L" better with no moving parts and automatic band switching, no need to fiddle with tuning. ...but, I am open to somethin

There is something unfortunately lost on many folks and that is that the most expensive is not always the best and the cheapest is often not the best bargain. Time and money... if you don't have the
