Why uplink only ?
Wherever possible it is desirable to have allocation that permit both Space-to-Earth and Earth-to-Space communications.

Would the allocation be for Uplink only?

Lets preserve 2m downlinks for OMNI directional downlinks to Mobiles and handhelds where the 19" mobile whip OMNI has a 9 dB advantage over 70cm and a 24 dB advantage over 2.4 GHz.
We can easily close the link to mobiles and handhelds with Omni antennas with 2 meter downlinks from space. I hope we Continue to develop this mobile satellite capability. PCSAT and ARISS packet system demonstrate this easily.
Bob raises a good point here.
What are peoples views on trying to get an Amateur Satellite Service allocation at 50-51 MHz ?
Granted omni antennas would be 3 times bigger than 2 metres but we would benefit from low path loss and low doppler shift ?
