I am seeking info on the dtv gs lnbf. Parameters says it is a bss circular 11.45-12.2 lnbf with local oscillator of 10.500. It was sold to one of my customers to pick up the dtv international pak on Galaxy 3 which is a linear satellite using only tp 15ku band. Will this lnbf pick up also Directv Brazil channels? How does a circular lnbf pick up linear channels? If this lnb is used with a first generation RCA receiver, can I see the international channels on Galaxy 3? Even though I have been in the satellite business for many years, I try to get help anyway I can, so would some good soul please explain in some detail for me about this new style (to me) DTVGS. drjohn
