Medium Frequency Direction Finding Loop

This loop antenna formed part of the Medium Frequency Direction Finder equipment fitted to Canadian ships for navigational purposes.

The two loops of the antenna picked up radio transmissions from shore stations or navigational beacons, and allowed an operator to determine the direction from which they had come. Ships' crews could then use this information to help establish their own position. Some transmissions from ships and aircraft, both friendly and enemy, could also be detected. The loops of this antenna could be prominently seen on many Canadian warships during and after the Second World War.
