Again, thinking to FD...
- My FT-847 predates bi-directional CAT i.e. no computer assisted Doppler - I may be the only one at the station i.e. no helper to man the antenna (Arrow), so I may need to do everything. - assume the transponder LEO birds
Has anyone tried this?:
1) mount a standard TV antenna horizontal 2) align the horizontal rotor axis 90 deg to the orbit tilt (inclination?) of the intended bird (so if the bird went directly overhead, a beam mounted on the mast would track) 3) but, mount the antenna on the horizontal mast such that it can be set tilted off the mast 0 to 90 degs to the mast axis (from horizon to zenith, and in practice set it to the maximum elevation of the intended pass) 4) operation: set the rotator (in 2) and aim the beam to the AOS point of the pass (in 3), pan the orbit remotely from the operator position. 5) the rotator axis and angle of the beam to mast would have to be set for each pass.
Do-able?
