in rec.radio.scanner: Here is how you go about this task. First, we need a support for the coax, especially if you have to run over 125 feet of it. this is usually done by running a cable from the tree to a post firmly embedded in the ground right next to your house. We then support the coax by whipping it around and around this cable, to take the strain off it. We literally wind the coax around the cable Bad idea - you're forming a pretty good choke at anything above VHF-lo. Use steel wire to wrap both the coax and the messenger wire (that's what it's called - it's usually 14k stainless "aircraft" cable) to each other. Suggestion for the climber: Assemble whole pipe and antenna on the ground, then when in position in tree, use rope to "haul" antenna and pipe up to your position. Start with pipe and antenna upside - down, and install first bolt , but not completely tight. then, climb a bit further up, and use rope to turn whole thing right side up by rotating on installed lag bolt. Install second lag bolt and tighten. Good if there's enough room between foliage, otherwise haul it up right-side-up. One problem - it sounds as if the coax is going to have to be long enough that, even with LMR600, it might not be better than an antenna mounted lower but much closer. |
