KM-4


3 dB VHF fiberglass antenna 1,0 m (3.3′) – Windex ready

 

The KM-4 combines all the technical features of the KM-3 antenna with the Windex type wind indicator support function, thanks to the special chrome-plated brass joint positioned at the top end. In a few minutes it is possible to position the pre-existing wind indicator or mount a new one, thus freeing up valuable space in the masthead. The KM-4 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-4 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-4 gives the same performance of its 1,5 m big sister (KS-22) thanks to a special tuning of its inner electrical system.

 

 

The antenna is supplied together with the hexagonal key to tighten the wind indicator (wind indicator not included – to be purchased separately).
