About choosing uplink and downlink frequencies for CubeSat 1 kg, 1 cubic decimeter mini satellites
Why most of the cubesats use downlink frequencies around 436, 437 MHz in the UHF 70 cm band and uplink frequencies close to 144 MHz in VHF - 2 m band?
( see also the detailed explanations from here: **broken link removed** )
According to Friis formula this choice seems illogical but maybe there are good physical reasons for it.
