1. [TowerTalk] Feeding a Quad (score: 1): Author: CubexCo@aol.com; Date: Thu, 24 Mar 2005 16:29:26 EST; Bob, The problem to be solved when feeding a multi-band quad is matching the impedance that each band presents. Typically 20m will range from 50 to 75 ohms, 15m 75 to 90 ohms and 10m typically is abo; /archives//html/Towertalk/2005-03/msg00797.html (9,459 bytes)

That pretty much says what I wanted to know (and a whole lot more!) It seems to me that a just reach length, or rather some arbitrary length close to that is going to be the best co; /archives//html/Towertalk/2017-11/msg00196.html (8,261 bytes)

Re: [TowerTalk] Feeding a quad (score: 1): Author: "Kevin Stover, AC0H" <kstover@ac0h.net>; Date: Tue, 21 Nov 2017 17:20:49 -0600; Cubex Quads recommends 1/4 wavelength 75 Ohm matching sections for each band. Might need 3/4 for the 10m driven depending how far from the relay box. So does this NCJ article. ncjweb.com/features/jan; /archives//html/Towertalk/2017-11/msg00208.html (9,544 bytes)
