Design and Performance of a Wideband Radio Telescope
> the 34-meter antenna was retrofitted with a tertiary offset mirror placed at the vertex of the main reflector. The tertiary mirror can be rotated to use two wideband feeds that cover the 0.5-to-14-GHz band.
Fine bandwidth if it really works.

Launch Method for Kites in Low-Wind or No-Wind Conditions
Use a bungee cord for the kit string. Stretch it and let the kite (and 
camera go).
Don't expect an extended flight time.
