Build your own wildlife or security VHF transmitters using our ready to use circuit boards. Just attach a battery and they'll start transmitting! Our transmitters are easily turned on and off using a small magnet and also include an activity sensor as standard. Small and lightweight - only 20 mm diameter and 1.6g. 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.
Although the settings cannot be changed by the user, we are able to adjust some of the parameters during manufacturing to meet a particular projects needs (MOQ applies). These include the non-activity period (1.5 seconds to 30 days), pulse spacing and total current (2.2 - 4.2 mAh). Please contact us to discuss your requirements further.
