101. [TowerTalk] Antenna eating tree (score: 1)
Author: "Jim Jarvis" <jimjarvis@verizon.net>

Unlike Charlie Brown's kite eating tree, the antenna eating pinoak yielded to a 2 ton come-along. The windom remains are down. Validates my 'soft-technology' approach, using two small bowlines, tied

Martin, AA6E, expressed concern about the rope or wire being in the crotch of a branch, and that a screw-eye would be better. And better for the longevity of the tree. I agree, Martin....but the ante

Last time I had to plug a cable-entry, I bought stainless steel wool scrubbing pads at ACE hardware. They were 3 or 4 bucks apiece. That was VT prices. Down here in NJ it's probably double that. N2EA

A friend of mine has a MonsterIR. There was a problem with the antenna whereby it got locked in some random configuration (not tuned for any ham band). It took something like a month of troubleshooti

Thanks, all for comments on this topic. I didn't buy the passive 6m element, because it constrained the 180 degree flip mode on that band, and because I felt the spacing was too far from optimal. Sti
