FW: [Antennas] Quick and Cheap

Tim,

Galvanised pipe will probably be very lossy. Owing to skin effect, most of
the RF current will flow through the zinc coating. Zinc is not famous for
its low resistivity and will certainly degrade quite rapidly with exposure
to the elements.

You will certainly be much better off with aluminium or copper tubing (my
spell-checker is set to UK English). Copper water-pipe will work fine.
