BTR-240 Base Station
The supplied omni-directional antennas have a circular antenna
pattern and radiate RF signals equally in all directions. When
using the omni-directional antennas, the base station should be
located as close to the center of the wireless coverage area as
possible.
The antenna placement and separation distance for the receiver
and transmitter is not adjustable when the antennas are connected
directly to the base station on the back of the unit. If desired, the
antennas can be remotely mounted or mounted on the front panel
for a better signal path. A coax assembly with remote antennas
may be required. See the “Accessories and Replacement Parts”
section for ordering information.
NOTE: Antennas should never be mounted on, or next to metal,
such as beams, walls with metal studs, equipment
racks, etc. This will “detune” the antennas, by altering
the antenna pattern characteristics, which can result in
noise or loss of RF signal at the base station. This also
applies to the antennas when connected directly to the
base station.
NOTE: If the base station is to be located in a shielded rack
mount enclosure or other poor RF location, the
antennas must be mounted remotely with coax
assemblies. See Figure 4-7 for antenna mounting
options when using in an equipment rack.

Equipment Rack Antenna Placement
1. Placing the BTR in a shelf or
equipment rack and using
remote antennas is OK.
2. Placing the BTR on top of a
shelf or equipment rack unobstructed
without remoting the antennas is OK.
3. Placing the BTR in a shelf or
equipment rack with the antennas
mounted on the back of the BTR
or the side of the rack is NOT OK.
