1. [TowerTalk] Interaction Issues (score: 1): Author: Jeffrey Cantor <k1zn@att.net>; Date: Sun, 9 Apr 2017 02:07:34 +0000 (UTC); I recently had some tower work done. Ihave a Rohn 25 tower up 60 FT. I have a C-3 and a 6-element Cushcraft 6Mon it. Both antennas were doing fine SWR essentially flat on the C-3and around 1.5:1; /archives//html/Towertalk/2017-04/msg00049.html (7,560 bytes)

First, try rotating the antennas to see if that affects the swr. If yes, it is a guy wire or something else external to the antennas. If not, try; /archives//html/Towertalk/2017-04/msg00053.html (9,900 bytes)

If the 6m beam is 90 degrees to the C3 and the 6m boom length is around 1/2 wl on 20m or less than that but electri; /archives//html/Towertalk/2017-04/msg00054.html (8,019 bytes)

Re: [TowerTalk] Interaction Issues (score: 1): Author: Chuck Dietz <w5prchuck@gmail.com>; Date: Sun, 9 Apr 2017 12:22:00 -0500; No reason to change the coax length, check the coax itself by disconnecting and putting an analyzer at the remote switch on the tower, if there is one.

I later read he meant that he rotated the 6m beam 90 degrees. I am not sure why he rotate; /archives//html/Towertalk/2017-04/msg00057.html (9,594 bytes)
