Shakespeare 4018-M 19' Vhf Antenna
Average Customer Review:
Shakespeare Style 4018-M VHF Marine
19' LENGTH, 9dB
PHASED 1/2-WAVE ELEMENTS IN A COLLINEAR ARRAY WITH A COAXIAL CHOKING SLEEVE TO SUPPRESS CABLE RADIATION
Same as Style 4018 with a special sleeve for mast mounting. Used primarily for land-based stations and on commercial vessels.
The top choice for charter boat captains and experienced sport fishing enthusiasts. This long-distance VHF antenna is rigid enough to stay erect in rough seas, yet exceptionally lightweight.
- Brass and copper elements
- Chrome-plated brass mid section ferrules and aluminum sleeve bottom ferrule
- SO-239 connector at base
- Suggested mount: Mast mount using supplied 1¾" U-bolts. The 4018-M can be strapped to a larger mast if steel banding (not supplied) is used.
- Two sections: Base 162"; Tip 66":
- Shakespeare Limited Warranty: 2 years
