I will use a pulley. The branches I want to use are very high. I cannot
throw or even use my slingshot thingy for this. I have a handyman who has agreed to climb the trees in the spring. I will get everything ready this winter. I have some large trees on each corner of my lot. I can probably get 50 feet up. I was going to use nylon rope to attach to the trees but I read that polyester rope last longer. It is even cheaper. I erroneously thought that the more expensive nylon would last longer. "Bob Miller" wrote in message ... On Tue, 19 Dec 2006 18:11:27 GMT, "B29" wrote: Thanks for the suggestion. I have decided to make my own. There are suggestions on the web that radio shack makes some good twin lead. www.thewireman.com is a good place to buy twinlead and stuff. However, I still would like to put up a balun. What would be the best balun for me? I intend to operate on 75 meters. I admit to being a ham since 1956. However, I have not been very active and now that I am retired would like to get on low band. I am not very knowledgeable on all the types of antennas. I do know how to make a random wire work but do not want that type of antenna again. Also, to keep the twin lead insulated, do I need to coat the ends where they are shorted? I do appreciate the successful reports of using this type of antenna. What might happen if I put an antenna tuner on the transmitter end and tried to operate a folded dipole for 75 meters on 40 meters? I cannot safely use my trees until they are thawed. I cannot climb them myself and I would not pay someone to do this until it is safer. You could attach a weight to a piece of rope or cord, throw it over a limb, and then hoist the end of the antenna up. Beats climbing, ice or not, and to adjust the antenna, you just loosen the rope, and let the antenna down. Bob k5qwg Michael "Denny" wrote in message groups.com... Michael, please do not spend good money for something you can build yourself for a fraction of the cost, and learn good things in the process... An 8X10 piece of plexiglass storm window from the hardware store will supply strips for the end and center insulators... A chunk of 300 ohm TV twin lead will supply the folded dipole material... A roll of coax, some solder, and a pieces of small rope, and you are in business... A hack saw will cut the plexi (so will a skill saw or table saw)... Why not make one for 10 meters as a starter until spring comes... This can be hung between two trees or whatever so it is at least head high and will give you some fun when the band opens here and there..... You can check the formula for length versus resonant frequency... denny / k8do |
