Re: LF: Re: Questions and resonating tests and measurements on a 700m wire antenna at 137 kHz (score: 1): Author: "Alan Melia" <[email protected]>; Date: Wed, 13 Oct 2010 00:11:37 +0100; Hi Stefan yes that could be a problem. I have a gut feeling that being short (in a vertical sense) they will be almost isotropic. You may need to get someone to drive around at about 5km to check tha; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-10/msg00276.html (17,622 bytes)

One more difficulty could be the different radiation pattern of the two configurations. So the signal difference at a specific location must be seen with care.

I believe this antenna is through trees and foliage. This may mean the measurements maybe not what you think they are. The voltage on the grounded end configuration will probably be lower.; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-10/msg00466.html (15,131 bytes)
