[Lowfer] antenna location

[Dick Goodman]

What I found with the AMRAD E-Field probe is that the chassis connector of
the SO239 coming out the bottom MUST BE GROUNDED!!! It doesn't even have to
be a good ground. A doggone 10 penny nail stuck in the gound seems as good
as a 10 foot gound rod. If you don't ground it, it's noisy as hell and it
plain doesn't work well at all.

Subject: [Lowfer] antenna location


Years ago, when I first started using an active e-probe antenna for
LF/VLF receiving, I placed it on a ten foot TV mast attached to a vent
pipe on my roof. The results were underwhelming, as noise (QRM) from
devices inside my house was quite strong. It wasn't long before I
moved my antenna to a spot in my yard about 50 feet from my house,
which produced much better results, and that has been my receive
antenna location for the various antennas that I have used over the
years. A couple months ago, we had a metal roof installed over the old
asphalt shingles. It just struck me today that the new metal roof
might provide an RF barrier for the QRM. I wouldn't mind having a
second receive antenna in place. Do you guys think I should try
putting one on my roof again, or should I just find another spot in my
yard?
