Hi,
I'm looking for any comparison which frequency select for cubesat (command, telemetry). I know that many of designers used UHF UHF, but link budget margin that better to use VHF - smaller path loss for about 10dB what are the main reason for use UHF --> antenna size, free frequency on UHF band, other losses, ground station antenna gain or ??
Thanks for help and comments,
best regards Andy
