Michael and BB,
Lou McFadin showed me a photograph a year or so ago of the S-band output
measured before launch, and it showed 1.2W out.
The antenna is a 1.2 GHz antenna tuned to also operate on 2.4 GHz, about 2-3
There is quite a bit of path loss at 2.4 GHz, but I imagine you have a good
preamp very close to the antenna.
