What is Left & Right polarization & how to receiver them?

What is Left & Right polarization & how to receiver them? Can I receiver them from the same LNB I'm using to get V & H polorizations? If it is, how?

 

[Analoguesat]

Left hand circular and right hand circular polarisation.

No you cant use a normal H/V lnb - you need a circular polarity lnb and a receiver that can cope with circ polarity too.

(Actually to be strictly accurate yes you can use the wrong type lnb although the results are spectacularly poor! Ive tried it! )

Hi kav4

Are you looking at C band (3-4 GHz ) or Ku band (10-12 GHz)?

Kav Bro , yes you can receive on the same LNB, Put a flat Teflon disc in the feedhorn mouth , Then you can able to receive circular signal .

Thx member91040. I have misplaced that Teflon disc. Is there any altanative I can use in place of that?

 

[member91040]

You can easley buy in the market or use glass flat disc.

ok got a disc. Now how should I set the transpondr to search. In the receiver I have only Vertical &Horizontal to select.
(this is not a blind scan receiver)

 

[member91040]

Put you teflon disc in feedhorn mouth, and try to auto search, Apply H & V as L & R .
