Hi all,
Given that people are currently working on groundstations for the upcoming HEO/GEO sats, I am in hopes that at least some of the following questions can be answered.
What kind of power will be required on the 5GHz uplink?
Does anyone currently make a linear amp or upconverter that can be mounted at the antenna for the 5GHz uplink?
Will I be able to use a helix antenna on the uplink or will I be limited to using a dish?
Same question with regards to antenna usage for 10GHz downlink.
What size dish?
With AO-10 and AO-13 I could point my antennas at the satellite and not have to move them for an hour or longer. These new sats will be using microwave frequencies. What kind of realistic expectation do I have of being able to point a dish at the satellite before having to tweak it? Otherwise said, will a rotator be absolutely necessary?
Thanks for the info. Looking forward to working the next generation of HEO/GEO sats.
