1. [TowerTalk] Phasing lines (score: 1): Author: "Tom Osborne" <w7why@verizon.net>; Date: Mon, 26 Sep 2005 18:55:43 -0700; HI all I have been looking high and low for my "Low Band DX'ing" book but can't find it. I want to re-do the phasing lines on my 3 40 meter verticals and can't remember what the length should be for; /archives//html/Towertalk/2005-09/msg00819.html (6,813 bytes)
2. [TowerTalk] Phasing lines (score: 1): Author: "Tom Osborne" <w7why@verizon.net>; Date: Sun, 01 Jun 2008 16:04:44 -0700; Hi All If 90 degrees is 360/4 (1/4 wave) then is 72 degrees 360/5 (1/5 wave)? Would that make a 72 degree phasing line 23.4 feet (133/5 * .88)? Then an 80 degree phasing line would be 26.1 feet (133/; /archives//html/Towertalk/2008-06/msg00023.html (7,413 bytes)

Coaxial lines can NOT simply cut coaxial lines to produce 72 and 80 degree phase delays in an array of phased verticals, because the; /archives//html/Towertalk/2008-06/msg00024.html (8,745 bytes)

Re: [TowerTalk] Phasing lines (score: 1): Author: ww3s@zoominternet.net; Date: Sun, 1 Jun 2008 21:47:45 -0400; To cut your 72 degree line using an analyzer, convert it to a freq where it's a 1/4 wave. For 7 mhz, a 72 deg line would be a 1/4 wave or 90 degree line at 8.75 mhz. easier to measure this way. Frank; /archives//html/Towertalk/2008-06/msg00029.html (10,992 bytes)

To make it general, just divide the desired (matched) phase shift by 360, then multiply this by the length for one wavelength. So for 72 degr; /archives//html/Towertalk/2008-06/msg00033.html (8,887 bytes)

Re: [TowerTalk] Phasing lines (score: 1): Author: Dennis Ventler <w9jdj@hotmail.com>; Date: Mon, 2 Jun 2008 06:49:03 -0500; I am surprised that no one on this reflector has never mentioned using a "T" phasor for phasing either two verticals or two horizontal dipoles. Yes, there is a very complex phases due to close proxim; /archives//html/Towertalk/2008-06/msg00037.html (9,179 bytes)

This can be done with two matching networks. The transmitter goes through the first matching network and; /archives//html/Towertalk/2008-06/msg00040.html (11,146 bytes)

What do those of you that have phased arrays do with your phasing lines? Just move them to mow? Remove them in the "off" season. Suspend them. Bury them.
