K4G 154A
Lotek KiwiSat® K4G 154A and K4G 154B are lightweight marine Argos transmitters for glue on attachment.
Each model is carefully designed with a compact shape, minimal frontal area and can operate up to depths of 500 and 200m respectively.
These tags maximize the benefits offered by the Argos-3 network meaning that transmit power can be halved for the same amount of data throughput and error rates, thereby minimizing the transmitter size.
Ideal for Penguins and other marine animals.
