[Lowfer] GROUND RESISTANCE

[rick]

Thanks Andy,
Appreciate the info.I just finished reading  Bill Ashlocks papers on loop 
antenna .I trhink thats the way Im gonna go .It seems like alot of work to 
get a decent ground and the xyl isnt gonna let me knock down the trees so 
Ill never really have ideal setup.
 Its nice up here on the mountain --just not for antennas!
