VHF Beacon Transmitter

Collars can be equipped with an independent conventional VHF Beacon Transmitter in the frequency range from 130 MHz to 260 MHz for tracking the animal. Its maximum output power is +10 dBm. This beacon additionally transmits two kinds of collar status information:

  • a mortality signal, if no activity has been detected for a pre-defined time
  • an emergency signal if battery power is low

The beacon transmitter is supplied by a battery independent from the main battery. Its operational lifetime is:

Battery PackExpected Lifetime
1C, 1D, 2D8,500 hours
3D, 4D, 5D17,000 hours
7D34,000 hours

You can decide at which times of the day your beacon is active – and save battery. This way you can configure the beacon to outlive the main battery and locate the collar via VHF telemetry after the sensors have run out of energy.

You can use your own beacon receiver to track the animal, so you do not need to purchase any new equipment.
