External Antenna Guidelines

Follow these guidelines when you install the antenna:

cMount the antenna as high as possible.

cTry to mount the antenna with a direct line of “vision” to the nearest cellular site.

cPlace the antenna vertically on a solid surface.

cBe 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.
