Hi Rich
I would give that a go.
Put the 3 EL Steppir at the top of the tower just above the thrust bearing and then add the LEO antenna and the elevation rotator at a height you can work at above the Steppir.
I think you would be pleased with the performance. I had done a similar installation for years with the 2M above the Steppir without issue taking into account all the normal tower cable running, etc.

Thanks. A LEO-pack might be a better choice for stacking then. Since the coax wouldn't hang down as far. Also less wind area...

That would work. Your AZ rotor will determine how big a HF beam you can install. Don't forget to add in the Sat array for wind load. The spacing will probably be determined by your coax feed to the Sat antennas.

I'm considering putting up a tower to get my satellite antennas off the ground. As long as I'm doing that, I'm considering putting a small HF
beam
up there too (maybe the 2 or 3 element SteppIR?).
Has anyone done that? Do you put the HF antenna below the AZ/EL setup? How much room would I leave between them? BTW - I have the larger M2 satellite antennas, not the LEO-pack, so the antennas are mounted near
the
middle of the booms, not at the ends.
I imagine I'd split the G-5500 into separate AZ and EL rotators, placing the AZ rotator in the tower.
Thoughts?
Thanks.
