Installation Notes
Choosing a Mounting Location
The location of the antenna is important. Objects such as metal columns, walls, etc. will reduce
efficiency. Best performance is achieved when transmit and receive antennas are mounted at the same
height and in a direct line of sight with no obstructions. If this is not possible and reception is poor, you
should try different mounting positions to optimize reception.
