[amsat-bb] Re: Mounting Elevation part of g-5500

[George Henry]

As David already mentioned, you may create drainage problems by mounting 
your elevation rotor horizontally...  if you want to block the existing 
hole, and drill a new one in the new "bottom" of the rotor, you may be okay, 
but "you pays your nickel, you takes your chances".

As far as "setting" the antenna position, the controller doesn't care how 
the rotor itself is mounted:  when the rotor is at the zero degree limit of 
its travel, you mount your antennas pointing at the horizon, and you have 
established the zero degree position.  Everything is relative from there.
