For what use?
Does anyone know if copper magnet wire would make for good antenna wire? Thanks.
Are you going to just monitoring, or will you be transmitting? Different uses dictate the type, and guage of wire that is needed. A good reference is the ARRL Antenna Book:
ARRL :: Antennas :: The ARRL Antenna Book
although a bit pricey at $44.95!
You might try getting a copy at a library and photocopying the pertinent pages, or you can look for a used copy at sites like Amazon:
Amazon.com: The Arrl Antenna Book (19th Ed./Bk&CD-ROM) (9780872598041): R. Dean Straw: Books
In my youth, I thumb tacked aluminum foil around the perimeter of my bedroom wall, up near the ceiling, and used an alligator clip to attach the lead wire to my short wave receiver and got good results, until Mom saw it

and told me to take it down!
If you are transmitting, you'll need a heavier guage wire, depending on the power level desires, and a way to match the output to the antenna, especially if it is a long wire antenna.
Google the following; "Matching long wire antennas" and see what pops up...lots of good info!
