Sat dish/receiver compatibility question

It comes down to size and feed assebly, bell/dish/dtv use circular polarization Ku-band (well mostly) Star choice and broacasters use linear C-band and Ku-band, if you want the master broadcast feeds and have a big dish you can use a dual band feed that will get both C-band and Ku-band linear, if you want you can get a wideband feed that does C-band linear and circular and Ku-band linear and if you want circular Ku-band then you can cut a hole in the scalar ring and slide a circular LNBF inside, though this will not be that good since it will be beside the feed throat and your positions will be off a bit for that.

If you do not have the room for a big dish, and want some Ku-band linear from the broadcasters then you will need a 90cm reflector or larger and a DVB pci card or box, if you would also like to get circular feeds on the same dish and less rain fade do to the larger reflector you can grab a invacom QPH031 LNBF this does both linear and cicular Ku-band.

The broadcast feed require a larger reflector because unlike dbs companys they do not use much power for there feeds.

To see many feed that are on both C-band and Ku-band look here:
http://www.lyngsat.com/america.html
Feeds from 3000-5000 are all C-band, feeds with freq over 11000 are Ku-band, when you see H and V this is linear, if you see L and R this is cicular.
