This is true however, it should be interesting to see power company behavior going forward as the FCC has recently ruled costs for finding source interference must be borne by THEM! Pete W2PM The bes

Nice work and good comparisons. However I think it's important to note that noise nulling effectiveness is subject to local conditions which encorporate TONS of variables, and variables of variables.

I've used edgers and they create a nice slice in the ground but it's still a chore to run the radials in same without staples. So I just staple the wires to the ground now in a grassy area. The lawnm

Here in NJ normal lawn grasses will completely swallow the radials next spring using the ground staples. But normal lawn maintenance will rip many up. Raking and even lawn aeration will cause damage.

There is person who is also a ham who sells radial staples -- they work very well and are dirt cheap -- something like $7 USD for a 1/2 pound bag of 315 pcs. He is (or was) on Ebay but his email is:
