These tiny collar transmitters are designed for very small mammals (mice, voles, etc.). Collars can also be configured for birds and bats.

Frequency Range: 148, 149, 150, 151, 164, 165, 172, 173, 218, 219 & 220 MHz only.
Transmitter: Crystal controlled two-stage design, pulsed by a multivibrator.
Pulse Width (standard): 20 milliseconds.
Pulse Rate (standard): 40 pulses per minute (ppm). Available from 20-120ppm.
Power Output: Set to use available battery power over the required transmitter life.
Housing: The transmitter and battery are encapsulated in biologically inert epoxy, to resist damage from abrasion and chewing. Battery placement determines shape. The unit is attached to a collar formed by the antenna or a separate wire collar or elastic. A TYGON sleeve covers the wire to prevent abrasion on the animal’s neck.
Antenna: A stranded stainless steel wire covered with a black nylon coating. The antenna may also serve as the collar on some models.
Activation: Soldering two wires starts the transmitter. Activation Instructions
Temperature (suffix “T”): An increase or decrease in temperature results in a corresponding increase or decrease in pulse rate. At the standard settings, the pulse rate changes from ~25 ppm at 0°C to ~40 ppm at 40°C. Each transmitter is supplied with a plotted calibration curve. This option adds ~0.05g to the finished weight of the transmitter.
Position (suffix “P”): The pulse rate switches from ~24 ppm in a vertical position to ~50 ppm in a horizontal position. This option adds ~0.5g to the finished weight of the transmitter.
