NTQB Coded Tags
Monitor all your birds and bats simultaneously with 0.29g coded radio tags
We supply and customize Lotek Avian NanoTags, the smallest coded transmitters available to bird researchers today.
Employing Lotek’s unique coded transmitter technology, these tags allow you to track and uniquely identify hundreds of birds on a single frequency.
The NanoTag’s field-proven, energy efficient design delivers a highly stable signal, while its diminutive size and long operational life allow ornithologists to collect data on smaller bird species, over longer periods of time, than ever before.
Avian NanoTag-series transmitters are designed for use with Lotek digitally encoded systems. Based upon a proprietary coding scheme, our coded telemetry systems allow hundreds of transmitters to be assigned on a single frequency, while retaining the ability to identify individual animals. This capability reduces the need for additional frequencies typical of conventional pulsed/ beeper systems. This results in an overall reduction in scan cycle time and corresponding improvement in the probability of detecting tagged animals.
Burst rate/intervals selected for the NanoTag transmitter can be specified in 0.1 second increments to best meet application and operational life needs. Specifying a daily activity cycle for the transmitter further extends operational life in mobile tracking studies.
Small size & weight
Allows smaller species to be tagged and monitored.
Hundreds of animals can be assigned to a single frequency.
Retains ability to identify individuals.
Increased probability of detecting individuals.
Designed for use with Lotek digitally encoded receivers, such as the SRX 800.
Infrared activation and deactivation
Eliminates need for magnet removal or attachment during field sessions.
Track birds with sub-gram tags for weeks or months.
A variety of options available to extend operational life with on/off cycles.
New high strength flexible antenna does not kink.
* Stated weight may vary by ±5% for minimum packaging. Much heavier packaging may be required for certain species.

Transmitter weight reflects that of complete device ready for field deployment. Intended for operation within temperature range of 0 to 35°C.
Notes on Operational Life
The burst rates and corresponding operational life specified for the transmitters are provided for comparative purposes. Various burst rates are available, based upon application specific considerations and operational life requirements. Typical operational life values are stated, based on component specifications and transmitter measurements, with warranty life expressed as 80% of the typical value effective from date of shipment.
