Hi Glenn,

I have a quadrafilar I use on 137.5 for satellites. It is built of SS flat
stock
rather than tube, but it works great. I have a preamp mounted near the base
of the antenna as well. I'd be glad to send you some pics and dimensions.
I doubt if there makes a difference using SS vs copper.

Over the years I have built several Quadrafiliar antennas for 137.5 Mhz
polar orbiting weather satellite photos. I have the dimensions pretty
well refined to get horizon to horizon reception but they have all been
copper tube on a PVC pipe. I have some 3/8" stainless tube left from
the watermaker project and thought I might use it and a piece of FRP
tube to make one that would hold up at sea. I have a couple of
questions about changing over to stainless but don't know where to ask
them.

There is plenty of info on the web but I can't seem to find a newsgroup
or forum to ask questions. Anyone else here dabble in quadrafiliars?
