I am operating on satellites modes A and B using simple crossed dipole
antennas, but am now considering making a helical antenna for 70cms.
What sense of circular polarisation, right or left hand, generally
gives the best results assuming the satellite is not using circular ?
I guess that two helical antennas, one for each polarisation direction,
would be the best solution.
Do any currents sats, qrv on 70cms, use circular, due to antenna type
or spin ?
