What is VHF? VHF is short for very high frequency, it usually means radio waves between 30MHz to 300MHz, suitable for short range signal transmission. A receiver with antenna can receive signals from a VHF transmitter. A VHF transmitter is reliable and highly efficient in performance.
Wildlife telemetry tracking systems consists of VHF transmitters, antennas and receivers. An antenna and a receiver must be combined to receive signals sent from a transmitter. We do various kinds of transmitters for animals and bird of different weights, body sizes and living habits. (many types of transmitters are available, collar transmitters, implantable transmitters and transmitters for reptiles and amphibian animals) Features and Functions of a VHF transmitter Battery life can be as short as about 15days and as long as several years. Implantable transmitters could be used for snakes, lizards and fish.
Transmitters weigh from 2.8g to 35g. Often used on raptors, sometimes on gulls and terns. Attached to underside of one to four tail feathers using glue and braided nylon fishing line. No harness around the neck, wings, or body to encumber movement. Body growth of young birds not a concern since transmitter is attached to tail rather than a growing part of the body. Retention based on seasonal molting patterns. Recapture unnecessary since transmitter falls off when tail feather is molted. Weight requirements limit field life. Possibility of premature feather loss exists, reducing time a bird can be monitored.
