[amsat-bb] Re: Suitsat I signals

[Achim Vollhardt <avollhar@xxxxxxxxxxxxxxx>]

Hi Bob,

I would recommend two quarter-wave antennas.. one at the helmet and one 
at the chest, perpendicular to each other..

I guess we have to keep it as simple as possible.. the more complicated 
it is, that less chances it gets to fly.
