Mounting your VHF antenna at the top of the mast gives you the maximum possible antenna height — and with VHF radio, height is range. The 2-piece design makes it practical to run the antenna up the mast and assemble it in place, while the mast-mount configuration keeps your deck clear and your signal unobstructed in all points of sail.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e8 ft (96\") overall length — full-size antenna for maximum VHF range\u003c\/li\u003e\n\u003cli\u003e2-piece construction for easy mast installation and cable routing\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for masthead mounting on sailboats\u003c\/li\u003e\n\u003cli\u003eTuned for the international VHF marine band (156–163 MHz)\u003c\/li\u003e\n\u003cli\u003eDurable fibreglass construction rated for permanent offshore exposure\u003c\/li\u003e\n\u003cli\u003eStandard connection compatible with coaxial cable feed through the mast\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e The 399-1M is the right choice for sailors who want to maximize VHF range by mounting their antenna at the masthead rather than at deck level. Masthead height on most sailboats puts the antenna 50–60 ft above the waterline, which can more than double effective VHF range compared to a deck-mounted antenna. It’s particularly well suited for offshore and coastal passage-making where range to coast stations and other vessels matters. If you’re also running an AIS receiver or transponder, consider pairing this antenna with the \u003ca href=\"\/products\/shakespeare-5257-s-vhf-antenna-splitter\"\u003eShakespeare 5257-S VHF\/AIS Antenna Splitter\u003c\/a\u003e to share a single masthead antenna between your VHF radio and AIS unit.
