Telex FMR-10, WT-10 operating instructions Antenna Placement

3.1.2 Antenna Placement

For any wireless system to perform correctly, strong RF signals are mandatory. To maximize signal strength, good antenna placement must be utilized. Although some situations prohibit perfect antenna placement, here are some guidelines:

1.The antennas should be placed in a location with a clear signal path to the transmitter. Walls, ceilings, metal objects, equipment racks, etc. are all signal barriers that will reduce range and perfor- mance. Generally speaking, placing the receiver at an elevated lo- cation can help increase range and signal strength.

2.If the receiver is rack-mounted, external antennas are neces- sary. Do not rack mount the FMR-10 with the antennas mounted directly on the back of the unit. This will severely decrease the range and performance of the system.

If the FMR-10 is rack-mounted, make sure the antennas are front-mounted (following the directions noted above). If anten- nas are mounted remotely from the chassis, the 1/4-wave anten- nas supplied with the receiver cannot be used. 1/2-wave antennas are a necessity if the antennas are remote-mounted and can pro- vide better performance when used with the rack mount.
