Topband: Strange behaviour of radial systems (score: 1): Author: "Kees Nijdam" <clnijdam@knid.nl>; Date: Mon, 16 Feb 2015 18:33:14 +0100; I have a north-south switchable 21m high phased pair for 80m with 1/8 lambda spacing. It is optimised for 3520 kHz, the feed -Christman-system was made according to ON4UNs book and software. Measurem; /archives//html/Topband/2015-02/msg00493.html (8,476 bytes)

Just the fact something is not resonant does not mean it isn't a problem. To my ashtonishment, vertical 1: 28-j328 Ohm and vertical 2: 12-j320 Ohm both on 18; /archives//html/Topband/2015-02/msg00497.html (9,177 bytes)

At 50m distance of both verticals I have a 16m high tower with a 3 el Steppir. This tower has a radial system and is shunt-fed tuned for 80m. There is some interaction; /archives//html/Topband/2015-02/msg00499.html (11,184 bytes)
