The KS-21 is the perfect antenna for small boats and RIBs. With only 100 cm length it guarantees the same performance of a 150 cm length VHF antenna. 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.
