SIKA Radio Tracking Receiver

We have developed a highly sophisticated receiver able to cover from 138 - 174 MHz. Despite it's compactness, it has all the advantages of storing and scanning frequencies and is more waterproof than any other receiver designed for radio-tracking. Currently we have a high demand from satisfied customers. Therefore please contact us (info@biotrack.co.uk) to get you a lead time.

  4 MHz, 8 MHz or 30 MHz bands available
Sensitivity -150 dBm (min. discernible signal)
Battery Life 24 hours (rechargeable battery)
Size of box 150 x 85 x 55 mm
Weight 800 g (1.8 lb)

Sika Functions
  • Programmable memory (256 channels)
  • Scanning (1 - 999 seconds)
  • RS232 control
  • Analogue and digital gain
  • Signal strength indication by bar graph and numerical readout

DataSika Data Logging Receiver

The DataSika is a practical and user-friendly datalogger, designed for autonomous data collection of presence/absence, migration through an area or the logging of activity/temperature. The DataSika has an extremely tough, waterproof housing to withstand long-term deployment in adverse conditions. Up to 20 traditional tags on different frequencies can be monitored sequentially, or over 200 coded tags on the same frequency can be monitored simultaneously; increasing sample size and reducing the chance of missing an event. Please contact one of our biologists (info@biotrack.co.uk) to discuss which version would best meet the needs of your project.


DataSika Specifications

Frequency band 4 MHz (148-152 or 170-174 MHz)
Audio Sensitivity -150 dBm (min. discernible signal)
Logging Sensitivity -135 dBm (min. discernible signal)
Logging tolerance Peak over 4 kHz
Battery Life

External Battery Required

  Coded technology reduces the chance of missing an event when logging, because the logger does not have to scan through separate frequencies.

 



Yagi Antenna

Biotrack supplies two models of Yagi antenna. Both antennas give excellent performance, and are light-weight and robust. One Yagi has conventional rigid elements, and the other has flexible elements that fold on impact and automatically spring back into position afterwards. In common with most good Yagi designs, these antennas are 'matched' to the standard 50 ohms input impedance of radio-tracking receivers. However, the matching is achieved by 'inductive coupling' via internal windings that are sealed within the central element. This avoids the need for a more cumbersome external device such as a gamma-match.

Software

RANGES software allows easy analysis of locations, whether animals, humans or plants. If you need to determine animal home ranges, analyse dispersal, decide which habitat is most often used or how animals arrange themselves socially, RANGES is an invaluable tool.
