Antenna support lines that is, a rather mundane topic but FWIW...
Took advantage of the nice WX today to do some springtime maintenance on my half-dozen or so outdoor wire antennas. They were installed at various times in the past with whatever was on hand at the time. The stuff that was in the worst shape was the offshore made loosely woven nylon line. It had pretty much decomposed in the UV. OTOH, the made in USA tightly woven white nylon line was in great shape. It seems to last forever. Surprisingly, the poly stuff from the dollar store that holds up the 10 meter dipole looked almost brand new. It has been up there since the last time 10 meters was good (quite a while). However, it is difficult to tie a good knot in the poly line.
Anyway, replaced the deteriorated nylon line with some black Dacron double braided line. Looks like nice material. We'll see how well it holds up.
