Product source ↗The MM-27 is a manual antenna matching unit for 26 to 28 MHz. It changes the impedance presented to the transmitter to improve matching of the connected antenna system. Its compact metal housing connects into the feed line through two PL sockets.
Adjustment is checked with an SWR measurement. Better matching at the transmitter does not automatically eliminate losses in an unsuitable antenna or make it radiate efficiently on additional bands.
