That support rope Jim referenced has done a great job here for a number of years supporting wire antennas over 100 feet long hung in tall fir trees. I did provide strain relief - a pulley at one end attached to a weight so the tree can move freely. We do get winds gusting over 60 mph here most winters and the rope has handled the shock load of the tree whipping and jerking on a 20 lb weight.
The wire I use is hard drawn stranded copper. I purchased mine through Ham Radio Outlet back when I lived near one of their stores. It is also on line at: http://www.hamradio.com/detail.cfm?pid=71-001462 73, Ron AC7AC -----Original Message----- Pulleys yes. Cord at a marine store will be expensive. Here's a link to the company that makes great antenna rope that is resold by several large ham vendors. 3/16-in is enough for strength, but 5/16-in is easier to grip if you need to pull it to put a lot of tension on it. http://www.synthetictextilesinc.com/supportham.html > I would recommend using hard drawn copper for the wire rather than > THHN. You can find THHN at your local DIY store. For hard drawn > copper, look at The Wireman www.thewireman.com. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
