LEAKY FEEDER CABLE

PBE’s Leaky Feeder cable is used to transmit/receive or
distribute RF signals throughout a confined space. PBE’s Leaky
Feeder cable is a coaxial cable with a specially designed outer
shielding that allows RF signals to leak and enter the cable.
It also allows signals from radio transceivers located nearby
to enter and travel along the cable to the base station. In a
confined environment, the power radiated from the cable is
limited to 10 mW to prevent the RF energy from interfering with
electric detonators. The cable has a radiation pattern of 360
degrees.
The leaky feeder cable is supplied on 350 meter spools (blue or
yellow outer sheath) or 500 meter drums (yellow outer sheath).
There are printed length indicators on every meter of the cable
to assist in cable layout.
PBE’s Leaky Feeder cable has a foam dielectric, which not only
makes the cable more robust, it prevents water from entering
the inner core of the cable. Air dielectric leaky feeder cables
have a ‘hollow tube’ which if damaged allows water to rundown
the cable and damage system components.
PBE’s Leaky Feeder cables are branded proprietary designs
that are manufactured to PBE’s specifications for use with PBE
amplifiers and ancillary devices which use saddle and clamp
connectors.
