Aluminum strip, 10 inches wide and .006 inches thick as a dipole.

How long?

Any special considerations?

How long you are to make your dipole, and what frequency do you intend to
operate?

How can I predict the band width?

In general wider and thicker produce wider bandwidth. Short dipoles or
long
ones in terms of wavelength may have reduced bandwidth because of
limitations
of matching devices.
As you know, bandwidth does not mean a good antenna. A resistor can
have a
huge bandwidth, but radiate very little.

40 meters is the primary, there is enough space to do a full length dipole
with folded ends (about 12 to 15 feet. If it works I wanted to put a 20
meter dipole in the other side about three feet higher up the rafters.

I am familiar with wire antennas, and matching, but have never tried using
sheet stock as an antenna below 10 meters, and that was is an apartment.
