[Fwd: LF/MF Antenna Proposal]
Tue, 26 Jan 1999 03:53:39 +0000 (GMT)
This may have some promise for our field trips as an LF transmitting

readio club that would like to help us try it out locally before we
travel off to some remote site.
I doubt it would contribute much to our receiving ability base on our Nags
