Hello:

Do listening only.

Presntly using a random length wire strung around the 4 sides of my attic
(probably about 40 ft x 25 ft x 40 ft x 25 ft; resultant loop left open at
end)

Works fairly well, but would like to try and do better.
Might bite the bullet this spring, and try putting something outside.

Whatever I try, I want it to be omni-directional, and be fairly broadband in
freq. coverage; say from 500 KHz to 30 MHz.
No Tower.

a. For something relatively straightforward, what type or brand would you
suggest ? Worth doing over what I now use indoors ?

b. Any probable advantage to taking the most simple approach, and ust
stringing a 150 foot straight wire outside
compared to what I now have in the attic, assuming same height.

c. regarding nearby lightning strikes and resultant voltage surges picked
up by the indoor antenna wi
does the house roof off any meaningful protection (when dry) compared to
a wire strung outside?

BTW: For a straight 150 foot wire, at a height of about 25 feet, is it most
sensitive perpendicular to the wire axis, or along it ?
How does the answer depend on received freq. ?

Much thanks,
Bob
