Introduction The PB3 is a covert, VHF, dual-mode beacon/alarm transmitter housed in ultra-lowprofile package. It incorporates 3-axis motion detection and a breakwire circuit. A single microprocessor controls all functions, allowing the beacon to be very compact. The RF power output is 1 watt. A screw-type terminal strip allows solderless connections, making it "field-friendly". Description Battery The PB-3 will operate from any 6-volt source.

The alarm is the same for both beacon transmitter mode and alarm transmitter mode. It is a 50% duty cycle, 1 kHz tone transmitted once per second. Antenna The antenna connector on the PB-3 is an MMCX. Various wire antennas can be used with the PB-3; it has an SWR tolerance of 12:1 (or better) . The wire antenna shipped with the unit is optimized for the frequency of operation. Ideally, it will be kept stretched out and away from metal objects as much as possible.
