Product Information

The End Fire Couplet Array (EFC/DD) incorporates a very high front to back ratio which reduces any unwanted signals arriving through the back of the antenna. These antennas are very robust and manufactured to a high degree of Telecommunications specifications. The EFC/DD's are fabricated from one piece of tube which eliminates the possibility of any high resistance points and the internal balun is completely seal moulded in black carbon-loaded polyethylene. The EFC/DD antenna would suit applications such as coastguards where no back signal is required and minimum interference.
