Terry is correct.
We manufacture and market a Loop Interface Box (LIB) that will work for AMB20, AMBrc and RC4 transponder systems. Basically any AMB or Mylaps system that uses a PASSIVE Detection Loop.

The box contains electronics to ensure the Detection Loop works correctly.
If you do not use the correct LIB then your detection loop will not work optimally.

We are about to phase out the standard chunky model (2 left in stock at time of posting) and replace it with a slimmer model.

It features large Green binding posts for easy connection of loop wire and BNC for connection of coax cable.
