elko,

Nothings invisable if you have a spectrum analyzer !

If you have a look at SatBeams.com you'll see there are
quite a few Sat's that have Ka band capability both linear
and circular but are not licensed for video.
They all ( except DTV ) see the Ka band as Internet only.
I saw an article on line written by the president of DTV
regarding the Ka band, he said that conventional wisdom
that Ka band was impracticle for video is totally false.
He felt that this attitude gave DTV a real advantage over
those other guys !

You can afford my Inverto LNB....... I'll take $40.00 + shipping !
