External Antenna Guidelines
OMEGA Installation, Operation, and Maintenance Manual 51
Follow these guidelines when you install the antenna:
c
Mount the antenna as high as possible.
c
Try to mount the antenna with a direct line of “vision” to the
nearest cellular site.
c
Place the antenna vertically on a solid surface.
c
Be sure that the antenna perimeter is clear of objects, especially
metal ones, that might interfere with the signal transmission
and reception.
Determining the Best External Antenna Location
Regardless of which type of external antenna you use, reception
and propagation patterns vary with the location. To achieve the
best results, try different locations. Even if a location appears
adequate, you should try other locations in case you find a better
one. Once you find the best location, permanently mount the
antenna there.
Use the OMEGA configuration application to evaluate the cellular
telephone’s receive line signal strength and ascertain the best
external antenna location. When the signal strength is –90 or
higher, you have achieved a minimum acceptable cellular signal.
