[Lowfer] GROUND RESISTANCE

[Peter Barick]

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.
