Whether for tracking wildlife or used for security of remote equipment, our VHF transmitter circuit boards are have a battery attached and encapsulated. Our transmitters are easily turned on and off using a small magnet and also include an activity sensor as standard. Small and lightweight - only 25 mm diameter and 2.0g. These boards accept batteries to allow them to transmit continuously for up to 1000 days. Available in many frequencies in 150, 151 and 173 MHz ranges.
We do not sell our transmitters boards directly from our website so please contact us to order or discuss your requirements further.
Since launching our range VHF wildlife transmitters we are often asked if we can supply the circuit boards without any encapsulation or attachment materials. This not only allows the user to design and build their own attachment method to better fit their study species but it also saves them money! We have also supplied the transmitter boards for attaching to other equipment. In addition to being attached to a wide range of wildlife equipment to help locate it after deployment e.g. drop-off cameras and GPS collars, our transmitter boards have also been used as an inexpensive, discrete and long lasting security device for remotely stored equipment such as farm and construction machinery.
