I need someone interested in adding quadrature 2 meter antennas to the outside of a 10" diameter sounding rocket by middle May...
This launch is going to space (100 miles up) from White Sands on a sounding rocket to then come back down by parachute. Antennas cannot stick out far (maybe an inch?) but can be bent back along the surface. Temperatures will approach 800F during the 10 minute flight. G' forces will be huge.
The payload will be (what else) an APRS trackign system and 2-way APRS communications transponder.
So, if anyone wants to take on this antenna, lemme know. All I need is the detail design and analysis. The machining is paid-for. Oh, it also needs quadrature GPS antennas, but that can just be a pair of 1.5" monopoles...
