Lucoro Dual Directional Test Coupler. A new test coupler intended as a lower cost replacement for the now discontinued EME 7020/30B. It allows precise measurement of transmitter forward and reflected powers. It not only works at FM and DAB frequencies, but is also ideal for use at 145MHz 435MHz and 1275MHz. Suitable for commissioning tests for UK Ofcom licensed radio stations.

DIRECTIONAL COUPLER

DC01/N/F-M

Most FM and DAB broadcast transmission systems are required to have a Dual Directional Coupler installed. This is a regulatory requirement to allow system commissioning checks to be performed, and must also remain in place so that the measurements can be checked and compared again in the future.

The Ofcom Site Engineering Code for Analogue Radio Broadcast stipulates that the Coupler must have two (dual) ports, so that both Forward RF and Reflected RF parameters can be tested without interrupting the broadcast.

This Coupler, while comparitively lower in cost, is made in the UK by Lucoro Broadcast. It allows measurements to be made and uses quality parts to ensure good power handling, a long service life and repeated accuracy.  More...
