Rick,
One thought - I'd be very concerned about RF getting into the entire house
system, especially stereos and tv's, depending on how your "radials" align
with house wiring and how proximate they are. I had a dipole 15 feet off the
roof of my house and at 1 KW, it wasn't a pretty sight...burglar and fire
alarms going off, night lights blinking (the KW is on a separate 220 line),
stereo speakers talking donald duck...the whole house rebelled. So now I am
repositioning it out in the back pasture. The only alternative is QRP!

Regarding the potential hazards involved in using raised radials on a
vertical - I'd be interested in comments from readers of this
newsgroup.
The antenna installation proposed is a vertical installed through the
roof of a building. For many reasons it would be preferable to keep
the radials inside the attic. My concern is possible danger due to
the high voltages incurred at the ends of the radials. The antenna
will be a SteppIR vertical for 40-10 meters with the base just under
the roof, protruding through the roof. At the base will be a number
of resonant radials fanning out throughout the attic. My concern is
if this poses a fire hazard due to arcing (corona, whatever) at the
ends of the radials. It may not be convenient to suspend the radials
over their entire length or provide high quality suspended insulators
at the wire ends. So what danger is there in letting radials lay on
the floor of the attic, attached to the roof rafters, or even poked
down inside the studs of the walls? I think we can assume the attic
will be dry, except for normal Seattle humidity !!
