DO NOT - mount the BTR-300 5/8-wave an-
tennas next to metal such as beams, walls
with metal studs, equipment racks, etc. This
also applies to the antennas when assembled
directly to the BTR-300. This will “detune”
the receiving antenna which can result in
noise or loss of RF signal at the BTR-300.
See Figure 17.

is GOOD.
2. Placing the unit on top of
a shelf or equipment rack
unobstructed without
remoting the antennas is
GOOD.
3. Placing the unit in an
equipment rack with
the antennas mounted
on the BTR-300 or the
side of the rack is BAD.
