Hi Terry,

I would try to get copper or brass screen instead of aluminum even though it
is expensive. The advantage is that it is easier to bond the pieces together
with solder to make a good electrical connection. Poor bonding between
sections could create points of rectification, which would tend to radiate
all kinds of garbage. The aluminum could work if you are very meticulous
about bonding, but copper/brass is much easier. The aluminum will not catch
fire. If you use wooden support structures, make sure that it is inside of
the screening and well covered (very extreamly important at the corners
which tend to attract more hits). I have only seen copper and brass (most
common) screen used at the transmitter sites I have visited.

Good Luck,
