Hi Tom, For VO-52 it is best to use LHCP (2 meters) for the downlink and RHCP for the uplink (70 cm).
AO-07 has linear antennas but LHCP seems to be best most of the time for the downlink. It all depends upon the satellite - not necessarily on the mode. Adding switching is a good idea. 73 OZ1MY/Ib -----Oprindelig meddelelse----- Fra: [email protected] [mailto:[email protected]] På vegne af Tom Gentry Sendt: 17 July 2012 05:11 Til: [email protected] Emne: [amsat-bb] Circularity question. Do I go RHCP on the downlink and LHCP for the uplink or vice versa for Mode B? I may add RH/LH switching later but for now my new antennas will be fixed. Is there a reference that speaks to this issue? 73, Tom K5VOU _______________________________________________ Sent via [email protected]. Opinions expressed are those of the author.
