VHF Radio: Coded Transmitters

Digitally encoded radio tags offer a distinct advantage to researchers because each coded tag transmits a distinct, unique numerical code that differentiates it from all other tags, even those transmitting on the exact same frequency. This permits monitoring studies to be done on large groups of individuals using a single radio frequency.

NanoTag Series Microprocessor-controlled coded radio transmitters.  A very small, highly stable and field proven radio transmitter that’s ideal for use as a smolt tag.	Avian NanoTag Small, long-life coded radio transmitters specifically for avian research. Avian NanoTags are the smallest coded transmitters available to bird researchers today.
MCFT Series Microprocessor-controlled coded radio transmitters. Track up to 521 transmitters on a single frequency, while retaining the ability to identify individual animals.	SR Series Microprocessor-controlled coded radio transmitters for use with Lotek’s SRX 400A / SRX 600 radio receiver family. Includes models with motion, temperature, and pressure sensors.
