Just about anything works better than the Pringles(tm) can that made
the antennas famous. I made one with a large fruit juice can and it
worked fairly decent. I picked up about 10 db compared to the stock
antenna.

Ditto,but mine was a clam-chowder can,IIRC. Got funny looks walking down
the soup aisle with a tape measure..but I found a can with
nearly-perfect diameter.
