4.3 Interface Cables and Antennas
Interface Cables
Pyramid Communications offers pre-made cables for the most popular mobile radios. If not ordered for a specific
mobile radio, the WB-1000 comes with a ‘blunt cut’ cable, which will allow interfacing to virtually any mobile radio.

Antennas and Antenna Placement
The WB-1000 comes with a unity gain whip antenna. Use of this antenna will provide limited coverage from the
vehicle, depending on the placement of the WB-1000 and vehicle configuration.
External antennas can be used, so long as low loss coax cable is used and the overall antenna system gain does not
exceed 2.2dB (including line loss).
Additionally, it is important that proper antenna placement practices are adhered to. The WB-1000 antenna must
be greater than 4 to 6 feet from the mobile antenna, on a separate ground plane, providing as much isolation from
the mobile transmitter as possible.
