3 db VHF fiberglass antenna 1,0 m (3.3′) length


The KM-3 is a masthead antenna with high performance and great robustness. It’s built with a 1,4 mm thick fiberglass whip that gets fully foam injected with the special Scout 100% waterproof technique, and it’s ice white colored with high gloss anti-UV filter to prevent color deterioration.

The KM-3 is equipped with N female connector, to optimize the signal transmission quality. It’s supplied together with a heavy duty 3 mm thick electropolished stainless steel bracket, that guarantees a perfect and stable masthead installation. Don’t be fooled by its length, with only 100 cm the KM-3 gives the same performance of its 1,5 m big sister (KS-22) thanks to a special tuning of its inner electrical system.
