Mike and all:

In a recent conversation with the camp ground owner, who also helped me put
up the support ropes for the antenna, he told me that their electrical
system had to be totally revamped within the past year, due to a lightning
hit they took back in the Spring of 2014.

Although the fact that they took a lightning hit within the past year and a
half does not make me happy, at least hopefully the system is now up to
code, if it wasn't before.

Regarding connecting a ground wire between the ground screw on the TS480,
and the ground screw on the power supply, I had thought of doing that, but
there is no such ground screw on the Samlex switching supply I use out here.

I have done some testing of the antenna out here this afternoon, and so far,
no RFI.  However, I do have an interesting problem which I'll report in
another post with a relevant subject line.

Subject: Regarding Tom's grounding question.

Assuming that the electric service connection to the motor home at Tom's
camp site is up to code, an AC supply plugged into an outlet inside the
motor home will be grounded to the service ground, just as it would inside a
house.

So, a wire between the ground screw on the radio and the ground screw on the
power supply would also tie the radio to the service ground.

While that is a good electrical ground, it may not be good for RF.

However, as has already been said, he will probably not have an RF problem
due to the type of antenna.

If he does, the old coil of coax trick should solve that problem if he
doesn't already have a 1 to 1 ballun, or a line isolator.
