[Lowfer] GROUND RESISTANCE

[rick]

Thanks Peter !
 Well the only spots on my lot that are treeless are where my house and my 
swimming pool are. I dont think the xyl wouild like an antenna in either of 
those spots.
 So yes I will keep you posted on my loop progress.

Rick,
Re: Your Antenna Choice

Given your assessment of local soil conditions (bleak) the choice most 
likely is a loop and based on Bill's proven works on the subject.

An easy choice appears to be a loaded vertical, but at LF performance is 
hard to come by, given the low power allowed (Part-15). From experience of 
setting up a LF vertical it's a big job and easily compromised given near-by 
trees and other conducting objects we people like to live with. Plus there's 
the ground radials, yes. need more than a few 10-foot ground rods at the 
feed point. I made a choice to lay out many on top of ground (a veritable 
land mine at night !). Yes it worked but at a higher cost of real estate, 
trees cut down and risk of RF absorption by yet other trees when sap is up. 
Ha, the one advantage left is the omni-directional quality vs the loop.

That's just my take, given my circumstances, of course. And it didn't begin 
with a grand plan -- just sorta evolved based on perceived need.

So if you have suitable trees and a means of dragging up a tow line at least 
50-feet high, go for a 50x50 foot loop. Oh, and keep us posted on progress.

Good to hear that Rick. No worries about tree loss or any significant
ground issues with the Ashlock loop. It will work. Keep those
connections perfect and use De-oxit or Vaseline on those connections so
they stay clean and low resistance. You will be impressed with the
loop's performance.
