Something I'm just wondering..
The narrow-band transponder uses RHCP on uplink and vertical polarisation on downlink.
The wide-band transponder also uses RHCP on uplink but uses horizontal polarisation on downlink.
Why is the downlink polarisation different?
Why is the uplink polarisation the same?
(I do see it's a lot easier to switch the polarisation of a LNB than of a circular antenna - still I wonder what the advantage is of different downlink polarisations?)
