Tracking and Other Equipment
[Sika] [Yagi Antenna] [Book] [Software]

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 Brian Cresswell (brian@biotrack.co.uk) who will be able to give you a lead time.

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.

Literature

This highly revised update of the classic publication by Robert Kenward will be the standard text in the field. New information on methods of radio tag harnessing, new sections on satellite tracking techniques and new types of data analysis are all included. Still the only comprehensive, up-to-date introduction to this fundamental technique for wildlife and behavioural biologists.

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.
