TVRO LNA's are a bit unstable for narrow band signal work. The two most
popular approaches to getting on Mode S are the SSB electronics 2.4 GHz
down-converter or the Down East Microwave (DEM) down-converter. I operate on
Mode S using the DEM setup. I use a three foot Ku dish (Wineguard) , a
DEM low noise preamp and the DEM down-converter. The preamp is needed
due to the length of coax between the dish feed and the weather proof
housing I use for the down-converter. The SSB reportedly is weather-proof
and can be mount at the feed point of the antenna. The cost of the DEM gear
is ~$140 for the preamp and ~200 for the down-converter, if my memory serves
me. The SSB system is about $400, as I remember. Down East Microwave
advertises in QST as does the US rep for SSB Electronics.
Good luck!
