Attempting to operate the wireless intercom
system through or around walls, ceilings,
metal objects, etc. will reduce system range

SIGNAL REFLECTION OFF A METAL OBSTRUCTION
CAUSES REDUCED SIGNAL AND “MULTIPATH”

Operating System Near Obstructions
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.
