[Lowfer] JAM copied last night

Heads up my e-mail carrier is acting squirrly. So if this gets scrambled thats why. So counterpoise
eh? Do you have local spys? If you look in my yard you will see about 80' of 12 gauge stranded wire
10' off the ground and zig zagging around my yard. I did attempt a tuned counter poise 2 years ago
but got stuck building the balum. Will finish when I get roundtoit. Right now the wire is doing
Redhawk predator counter measure duty. My wife has a bunch of little dogs. With the longwave antenna
and counter poise wire good luck nailing a Yorkie Terrier. AS to the MFJ ammeter. It's modified to 
work this low. You could probably derate it 25%. I use it as a relative measure. Did I get better or
worse. Descrition of my antenna. So first suggestion is to look at my youtube video from 09 I recall.
It's listed at LWCA on the "Community Forums" user setup catagory. In fact all the info suggested will 
be under that catagory. What has changed since I made the video is now I have 6 top hat radials and an
elevated coil to near the roof line. Also I have attached nearly 1500sq ft of concrete and dense rebar
to the ground system. You can view that as "Psudo Ufer ground" on the Community Forums at LWCA. In 
terms of ground radial I have about 60. Most go under the houes but about 12 run under the patio. I ran
them before the concret pour. Now I have attached the concret/rebar pour to the ground system as a
Ufer ground. Any questions let me know.
