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... "Roger Halstead" wrote in message ...

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.
