Scan-Antenna 11023-431 VHF23-1 Marine Antenna 3dB 1" Nut

Scan-Antenna VHF23-1 Stainless Steel Marine Antenna Kit

The Scan-Antenna 11023-431 (Model: VHF23-1) is a high-performance, lightweight stainless steel whip marine VHF antenna engineered specifically for sailboat mastheads, RIBs, commercial craft, and small powerboats. Featuring an ultra-slim stainless steel whip design, it minimizes wind load and aerodynamic drag at the top of a rig while delivering rugged resistance against extreme gale-force winds and marine salt corrosion.

This specific kit variant (11023-431) comes pre-packaged in a protective bag with Scan-Antenna’s heavy-duty 1" revolving nut adapter (1"-11 BSP / G1" standard), enabling straightforward mounting to standard European marine antenna mounts, deck flanges, or masthead brackets. Operating across the full international marine VHF and AIS band (156 to 162.5 MHz), it delivers a 3 dB (Marine) gain (0 dBd / 2.1 dBi) with an omnidirectional radiation pattern.

Key Features

• Ultra-Low Wind Resistance: Tapered stainless steel whip profile drastically reduces masthead heel moments and aerodynamic drag.

• Included 1" Revolving Nut: Pre-fitted with a 1"-11 BSP (G1") threaded mounting nut for direct attachment to standard marine brackets and deck mounts.

• Full-Band VHF & AIS Coverage: Broad frequency range (156 to 162.5 MHz) supports all international VHF voice channels, DSC hailing, and Class A/B AIS transceivers.

• Corrosion-Proof Materials: Constructed from premium stainless steel and UV-stabilized polymer components for extended service life in exposed offshore environments.
