VHF


VHF telemetry is an extremely reliable and cost-effective solution for wildlife tracking. It is still the only option for most of the studies performed on the smallest species.


Telenax is a leading manufacturer of VHF telemetry equipment worldwide. We have served the market since 2005 and we have a huge amount of returning customers because our units are among the greatest in efficiency and reliability, not to mention our Best Price Guarantee in which we commit to keep our prices at least 20% lower than any other wildlife telemetry equipment manufacturer.


Our materials are top of the line. The belting used on our collars is light, flexible, waterproof, with perfectly smooth and rounded edges, does not promote fungi growth, and are extremely strong (successfully used on bears). Our attachments and housings are carefully designed to be the least invasive and yet most functional. Our ear tags are very popular because they are shaped to avoid entanglement and biting from other animals. Our implanted tags use coiled internal antennas that are better for the animal and still achieve very good signal strength. We can customize the transmitters to find the perfect balance between strength and life depending on customer’s needs. We accept your preferred specifications whenever possible.


While its use requires human interaction, this is the most cost-effective, smallest, lightest and longest lasting option for wildlife tracking.



Also known as radio-tracking. Electromagnetic signals are broadcasted by the unit attached to the animal. These signals are received by a specialized wildlife tracking receiver and a directive antenna which allows you to determine in which straight direction the signal is coming from.



Tracking distance between animal's unit and receiving system:

- Up to 40 km (25 miles) under ideal conditions and strongest units

- 500 meters to 10 km (0.3 to 6 miles) in most real-life conditions, depending on type of unit, specie and local conditions. 


We offer some of the smallest radio tracking equipment available in the world. Developed with the greatest quality and components to withstand wildlife treatment. Customized to best suit your needs. 


Extra optional capabilities:

- Activity-Inactivity-Mortality sensor

- Posture sensor (between 2 customer-specified options)

- Water sensor

- Drop-off
