Nylatron is a very interesting material but there are MANY variations of the product. See this site for about 20 or so different "Nylatrons". It is NOT a variation of UHMW--but rather something compl
Jerry/Bruce-- Never use knots for Phillystran! And the Delrin block is "just OK" for a top boom guy--but NEVER should be used to structurally hold up a tower. For such a small tower (40ft of aluminum
I don't have my CQ mags at the new QTH yet, so I can't check the exact issue for the date that this antenna appeared on the cover, but, if I recall correctly, it was 13 elements on a 156 ft boom. My
Pete, I don't think you can have it both ways. If they are the same gain and one has a wider azimuth beam width it must have a narrower elevation beam width. That gain (power) has to come from somew
https://www.logsa.army.mil/etms/data/A/028953.pdf is the URL to go straight to the manual and skip the search hassle. But it was not working this morning. Site maintenance?? But I have directly acces
I sent this to Dino directly late last night--but I was reluctant to send it to Towertalk for a number of reasons. It was totally unedited--not even reread (still hasn't been) and I was tired last ni
Yield strength is a materials spec. Both Schedule 80 and 40 are the same material--so their material yield strength is the same. But the actual load they can handle is a function not only of the mate
When I got my first Rohn gin pole the hole in the pulley was SO off-center that the pulley would wobble and that would get transmitted to the gin pole itself. And the whole thing would oscillate back
Over 25 years ago I asked the people who MAKE the Nicopress sleeves about using them on 1x7 guy strand. They had never tried it and went out and obtained some 1x7 EHS and made numerous tests. One Ni
Mac has everyone on the right track but not quite there. You really want www.samsonrope.com for the site. I have always used somewhat smaller ropes such as the Samson Stable Braid series. 3/8 in is
Samson Stable Braid rope and Tenex rope I have received a number of requests for more information about Samson Rope. It can normally be purchased from major rope distributors in the larger cities. Ju
I mentioned some mods that improve the robustness of the KLM 4L 40M Yagi here on Towertalk and received a number of notes asking for more information. I will be working on that note later today and h
Sorry for the bandwidth--but this seems the only way I can reach Joe without bouncing. -- Joe, I have written you a few times but it always bounces-- Is there any other address that I can reach you?
Stan-- Thanks to NH6S we have discovered the problem is on my end. My IP has never properly set up their Reverse Resolve after they were acquired by another company and then that company was acquired
Don't think you actually have to hang the ROTATOR itself upside down. Just mount the normal top side to the fixed guy by using a short vetircal pipe mast welded to the center of a long horizontal pi
Here are a couple of short thoughts on tower ropes. 1) -- I prefer to use 3/8 inch and 7/16 inch BRAIDED rope (such as the double-braided Samson Stable-Braid rope that I previously mentioned, so that
Peter--yes this is a compromise--but as long as the cross pipe is significantly shorter than the driven element and the spacing is on the order of a few feet a meter or so (and the tree-to-tree suppo
W0UN notes on the KLM 4L 40M dual-driven Yagi I had enough requests to post my notes to the reflector so that they would end up in the archives that I have decided to go that route, rather than sendi
