18inch CP

[havenx]

Okay so I have this 18 inch dish with a CP LNB on it. Will it pick up the radio on EchoStar 7, and what is with the L and R? I have seen H and V and understand that but what is L and R?

 

[PSB]

Yes that dish will work for FTA DBS radio and the few channels (Gol TV / NASA..)
The L.O. should be set to 11250

L and R mean RIGHT and LEFT polarization.

Linear signals come down from the satellite in a straight line, horizontally or vertically.

Circular signals come down from the satellite in a spiral, left hand or right hand (polarized)

Have a look half way down this link for a diagram......

Is L and R a DBS thing for CP?

Added a link to the above to better explain and to help visualize.....

Is L and R a DBS thing for CP?

yep..Circular is mostly used in DBS. Doesnt matter how the LNB is, it works the same...cant do that with a KU band

as for polarity
R=Vertical
L=Horizontal
