I have an old shortwave radio and want a decent wire antenna
for it.
Would connecting a single insulated wire up through the wall,
through the attic and laid on the roof have a good chance of
working decently?
It will probably be about 125' from radio to the end of the
antenna.
I hope I don't need a ground at the radio.


it would be safer if you did ground the radio, exposing a wire outside is
just asking for lightning to come visiting.

If lightning does decide to stop in for a visit, what good will
grounding the radio do?
None. Might even make things worse. If you have an exposed wire in
the air, grounding the wire itself *OUTSIDE* to a decent ground, when
not in use, is the only safe protection unless you take more expensive
and complex methods. IE: gas tubes, ground windows, etc, etc. If you
direct lightning into the house, having the radio grounded will not
help you much at all. Grounding a radio in itself, is NOT lightning
protection in any form or fashion. MK
