1. Re: LF: RE: 80 meter butternut conversion (score: 1): Author: Andy Talbot <[email protected]>; Date: Thu, 9 Feb 2012 16:12:35 +0000; I have vertical of 7m height, with a top hat of 12m length making a T antenna. The capacity hat is made of three wires spaced by 200mm each. Total capacitance is 220pF and tunes with ~ 5mH. Groun; /rsgb_lf_group-archives/html/rsgb_lf_group/2012-02/msg00488.html (16,145 bytes)
2. LF: RE: 80 meter butternut conversion (score: 1): Author: Rik Strobbe <[email protected]>; Date: Thu, 9 Feb 2012 16:46:45 +0100; Hello Bob, as the antenna itself is resonant well above 136kHz it will have a very large capacitive component at 136kHz. Assuming it is a HF2V the antenna is a 10m vertical contruction, so using the; /rsgb_lf_group-archives/html/rsgb_lf_group/2012-02/msg00696.html (14,863 bytes)
