We can build antennas to customised dimensions to suit specific applications. There are upper limitations as to the size of these antennas so feel free to ring or email us with your specific requirements. The antennas can be multi-coil flat panel “swim by” or “swim under” or “swim over” antennas or single coil “swim through” antennas. The antennas are then tuned and linked to LID665, LID608 or LID650 decoder/dataloggers allowing storage of identification code, date and time data.
