Antenna Placement and 

Orientation

The supplied antenna is a center fed half-wave type 

with a right angle elbow and rotating mount. For most 

applications, the whip antennas should be vertically 

oriented to provide a circular coverage pattern. In other 

orientations, the transmitter antenna should be paral-

lel with and not directly above or below the receiver 

antennas.

Frequency Selection

For a single system, any of the four frequencies can be 

used for normal operation. With multiple systems oper-

ating in the same location, select a different frequency 

for each system.
Walk test each system through the area where it will 

be operating and listen for dropouts while observing 

the RF level indicator on the receiver LCD. It is best to 

have all equipment in the location turned on to check 

for interference and short operating range.
If the RF level on the receiver LCD indicates a weak 

overall level, try re-positioning the antennas. Re-ori-

enting the antennas or moving them even a few inches 

away from nearby surfaces can also make a difference.
If dropouts are experienced during the walk test, but 

the RF level at the receiver remains strong, there could 

be interference on that frequency band. Switch the 

system to another frequency and walk test the system 

again to check for adequate operating range.
