Myles,
AO51 435.300 is right hand circular polarization (RHCP).
AO51 435.150 is left hand (LHCP). If you try to hear
a LHCP signal with a RHCP antenna that is really right
hand, you will have a drop in signal that can exceed
20db. This will make the downlink unreadable at low
elevations. You
hi
Am in the planning stages of designing a satellite setup
and decided on M2 2m and 430 antennas.
They are RHCP out of the box , but I can buy a kit to enable them
to switch between that and LHCP.
It's kinda expensive and since I am inxperienced in this
