LF: RE: Earth electrode loop area - I'm struggling (score: 1): Author: Rik Strobbe <[email protected]>; Date: Fri, 18 Jun 2010 23:10:52 +0200; Hello Roger, my pennyworth: assuming - 50uW ERP - antenna is traded as a loop (gain = -0.4dBd) Due to the negative gain (-0.4dB versus dipole) a loop antenna must "radiate" 55uW to get 50uW ERP.

Jim is not far off the line of fire from the "loop", maybe 20 degrees off at most. 73s Roger G3XBM On 18 June 2010 22:31, Alan Melia <[email protected]> wrote: Hi Ro; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-06/msg00240.html (13,741 bytes)
