Don, I think you're setting yourself up for some problems which while
solvable are better avoided.
I've operated under the conditions you described, although at a
maximum of 500 W out. I didn't have a hot mike or other indications
of RF in the shack, but I did have problems with RF affecting the
computer, telephones and televisions which I didn't have in
an earlier installation where the station was at
ground level (although the distance to the antenna was about the
same). Most of the problems occurred at 500 W and were either
tolerable or non-existant at 100 W; some of the problems were not
caused by my setup but were power co or telco problems which were
fixed once I ascertained the cause. I was unable to fully fix the computer
problems.
Nevertheless, the biggest issue is grounding, both RF and for surge
protection. You *may* be able to get an adequate ground by using
wide (6") copper strap (#6 just ain't gonna cut the mustard).
You didn't indicate how far to the earth you'd be.
Make sure you avoid odd multiples of a 1/4 wave at ALL ham freqs. Again,
it sounds to me like you'd be better off staying where you are.
73,

Subject: [TowerTalk] Radio location in relation to antenna
I am considering moving my radio gear out of the lower level of
my house to the upper level. My reason is that I can convert a
couple of 30 amp circuts over to 220V I had installed to run my
computer gear when I first started my company. I don't need them
anymore.
The new location would put my gear about 15 feet under the roof
mount antenna I have just installed. I also have a couple of dipoles
layed across this section of the roof as well. I would be running an
amp rated at 1.5kw if I decide to relocate and fire up a 220V circut.
So what kind of RF problems would or could I be setting myself
up to experience? Would the proximity to the antenna pose a
problem? What should I consider if I do this? Should I maintain a
larger distance(55 feet now) from my antenna's such as I have
now? What precautions, RF wise, should I be considering? Will I
glow in the dark? :)
Any feedback or comments would be most appreciated.
Don
