Hi,

Your best antenna is a magnetic loop, not cumbersome at all (dia. 1m),
light, easy to install.
I tested the Wellbrook ALA 1530 ane 330 : very fine. (I kept it as spare
receive antenna)

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.
