Hi,
The data sheet of an antenna system can be found at http://www.tcs.la/Portals/0/TCSXY.pdf. This description is taken from it:
Our XY pedestal is ideal for tracking satellites in Low-Earth Orbits (LEOS) because it completely eliminates the problem of the overhead keyhole more reliably and less expensively than a three-axis system.
I just can’t understand what is “overhead keyhole”. Is it a term used in installation or something else?
