Hi Roger,
I'm beginning to think that some 2" tubing would be good at
the control end and half that at the winch (receive is the main interest)
would be the best way forward. I'm going to make some thing up and give it
a go.

Cheers, Malcolm...

Hi Jerry,
yes had thought of going directional, but have some small
problem. Him up stairs, keeps changing the wind so we have to move the
winch about the field. Some times this can be by 180 degrees ! So we are
restricted to omni-directional...

How about a discone? They cover a very wide range of frequencies and
are *relatively inexpensive. Probably on the order of $50 or so. The
simple Radio Shack model covers from about the FM broadcast band which
is well below the aviation band to over 440 MHz and are
omni-directional. There is a null directly overhead, but they seem to
do well. Otherwise I'd go with a ground plane and use a very large
diameter vertical element compared tot he regular size.
