installation, eg feedlines, other antennas, etc etc. I feel lucky - No rocket scientist here, I just put it together like the manual said, and the SWR was great as advertised. I even played with the parallel wire spacing (only because it has been a topic of conversation), but it wasn't that critical at my installation. Varying the wires from right next to each other or a couple of inches apart didn't make much difference. In the cases where getting them closer together solved a problem, it must be solving some interaction or cancelling out the effects of something else...?? I ended up with the antenna at 72 ft and a very long feedline (600ft), but the SWR curves were similar to those initially obtained at 30 ft height and 70 ft feedline. Mine is in the middle of a field. ----- Original Message ----- From: Natan Huffman <force12e@lightlink.com> To: F12Reflector <force12talk@qth.com> Sent: Friday, March 03, 2000 1:44 PM Subject: [Force 12 Talk] C31XR 15 meter VSWR > out of spec VSWR on 15 meters.
