1. Re: LF: ??? (score: 1): Author: Rik Strobbe <[email protected]>; Date: Mon, 07 Sep 2009 12:23:50 +0200; Chris, John, indeed, in theory radiation resistance is proportional to the square of the height (for a short vertical antenna). So "jacking up" the antenna even a few meter is worth the efford. As a; /rsgb_lf_group-archives/html/rsgb_lf_group/2009-09/msg00152.html (10,300 bytes)
2. LF: ??? (score: 1): Author: "Chris" <[email protected]>; Date: Mon, 7 Sep 2009 09:21:33 +0100; ....and how does 'Jacking up' the antenna increase the ERP? Chris, G4AYT.; /rsgb_lf_group-archives/html/rsgb_lf_group/2009-09/msg00346.html (8,364 bytes)

(score: 1): Author: John P-G <[email protected]>; Date: Mon, 07 Sep 2009 09:24:32 +0000; Chris,LF, Presumably by increasing the height one increases the capacity and the the radiation resistance and thus the ERP will rise for a given TX power and antenna current?
