    I had a similar problem on my 15M two stage tower, a section of the wire rope that is normally not visible around an upper pulley developed a bad spot of rust and fractures as I was lowering it. Luckily it didn't fall anywhere as far as yours, yes tower damage, however the antenna's were mostly unscaved, although not quite as straight as they used to be, I didn't have any 'aluminium rain' I live in a suburban block, so no massive HF beams that would hang over my fence line. VHF, UHF & the centre for inverted V style HF wire antenna's, and a camera - So I can literally say "I'm looking at you" as I swing the beams around. Paul VK3TGX

    I think the main lesson learned is actually a lesson re-learned - familiarity breeds contempt. It is too easy to not inspect everything thoroughly after a windstorm, and we all know it is a bad idea to be up in the air on a manlift while the tower is going up, especially without having spotter. "It's been fine for decades, so it is fine today" is the same as "I have always done it this way and never had a problem with it." Glad you are OK, and glad you shared this. We all need these reminders occasionally to keep us from getting hurt by our passions.

    You could collect that black sand from the gold mining guys and put that down over the radials. Or iron ore crushed up. Iron is cheap so if you knew of a foundry they may be able to provide an iron ore already crushed.

    I would like to see a demo of radials removed and reconnected on a relay while watching a weak signal on receive. Recently I contacted NZ from France on 11M Using a vertical on USB. At the time I had my vertical just above roof height and I have a large shallow metal roof. The antenna is on an 11m mast to ground but touching the ridge line of the metal roof. At the time It was at around 7M heigh and only just above the metal roof. However the metal roof is all to the North. Normally I would expect it to pull my Signal Northwards. We were on the longpath to NZ so perhaps being close to the roof helped. Also works great at 11M but I didn't hear NZ yet at that height (it's rare to hear NZ on 11M from Europe but can happen). My antenna is a loaded 5/8th wave with 20x radials at 90 degree to the antenna. Not the best antenna I've owned but not bad either.

    • @3beltwesty
      @3beltwesty 9 дней назад

      The radials on the ground if not connected will still help so a relay A versus B test for "receive" might not make a big difference. I am basing this on when was working skip on 11 or 10 meters with my car on the US 101 Freeway in California. A long distance chat to NZ would be OK then fantastic as one crossed over a metal bridge; then drop down into the mud when past the bridge. When parked in a vacant spot I had some copper wire radials to connect to the ground base on the 1/4 wave whip. The signals would be higher before the wire was connected up. With an swr sweep the bandwidth would be more with less radials since the lossy soil asphalt is like a lossy series resistor. I the backyard I ran a sweep test with a 1/4 wave whip and measured the swr adding lengths of #18 wire 1/4 wave. ie None; 2; 3 4; 8 ,16 32. The resonant freq shifts some and gets sharper with more radials. Had a mess of speaker cable in 18# zip cord. So for portable had 4 groups of 4 #18 single wires 12 and 16 ft. Too many got to be a rats nest; so used 4 wires going to 1 at the aluminum tapped whip bracket.
