What are L and R polarisations ?

[ashoknaik184]

Thanks for the info and ss.
I also came to know about Ku L and R polarisation from Lyngsat only.
If I am not wrong I think only Chinasats use Ku L and R polarisation ?
Does this mean that if we do not insert the teflon plate then there will be no signal at all even if beam reaches us ?

There are H &V and L & R both types of transponders on this sat first you try normal H/V TP with normal lnb. then try circular lnb without disturbing dish

In early days of Sun Network channels those were in L/R Polarities.. i think it was in Righthand Circular but cant remember the exact... i think it was from 54 / 55°E .. I was using this FeedHorn for getting the maximum signals using as Side corner  position in 12Ft Dish.. main was 83°E...this was specially made for Sun Network channels in early 90's...u can change positions according to L/R..

I am also using type of feedhon it gives more signal than Teflon Patti

Are these Ku LNBs ?
If so,Are these still available in the market or have they disappeared like previous  Gardiner C band LNBs ?

 

[ashoknaik184]

No they are c band circular polarization homemade

No they are c band circular polarization homemade

OK,
But I asked for info on Ku LNBs only.
