Install it with end insulators, for some applications a small piece of
dowel with the aluminum wrapped on it will make a suitable insulator.
Then tie off the dowel in the attic with 30 pound monofiliment fishing line.

The 10 inch width will give a wider resonance than a wire, assuming you
will be using it at 20 meters or lower wavelengths.

For an attic installation use nuts/bolts/washers to fasten the
transmission line to the antenna. Soldering to Aluminum requires much
more than simple solder.

Some time ago I obtained a roll of 6 mil thick 10 inch wide aluminum sheet
at a bargain. I intended to use it for an antenna in my attic. I would use
plastic clothes hangers as supports stapled to the rafters.

When I mentioned I was finally going to get it installed, a friend told me
that the sheet won't make a good antenna. There is plenty of room for a
bent dipole so I ask why he thought it wouldn't work. His answer was that
the thin edges would have a corona discharge and might set fire to the
house. I considered it nonsense, but I wonder -- Running only 100 Watts.

Is there any reason that a thin sheet of the proper length would be
unsuitable as an antenna for "indoor" use?

Thanks for you insightful comments.
