HOLOHIL VHF Transmitters

Product code: HOLOHIL


HOLOHIL VHF Transmitters

Holohil Systems Ltd. was formed to supply the wildlife research community with state-of-the-art radio-tracking equipment and related services. The extensive expertise of the personnel of Holohil enables us to provide an integrated service to the biologist on all aspects of wildlife radio-tracking.


Transmitters manufactured by HOLOHIL are custom-made for each order to suit your particular field requirements. Transmitter, battery and attachment configurations are designed for your animal and conditions. All transmitters are supplied finished and field-ready, batteries installed, completely encapsulated, ready to attach to your animals.

All HOLOHIL transmitters are crystal-controlled two-stage designs, pulsed by a CMOS or discrete multivibrator. We carry an extensive stock of crystals, covering the 138 to 230 MHz bands. The smallest transmitters (model LB-2X, LB-2N & LB-2) are activated by soldering two wires. All other models are activated by removing an external magnet, and deactivated by replacing the magnet. Temperature sensing, mortality sensing, activity sensing and position sensing options are available on most models, and more than one option can be added in some cases.

HOLOHIL specialize in the design and production of the smallest and lightest VHF transmitters currently available for a variety of species. One of them is the LB-2X. Weighing 0.27 to 0.31g and having a battery life of 12 to 21 days, the LB-2X is the smallest two-stage transmitter commercially available. The light weight of this new transmitter now permits the radiotracking of smaller species than previously possible. Our smallest transmitters, have been used to study small bats and songbirds, some of which are threatened or endangered species.
