Designed for use with Furuno VHF radiotelephone systems, it delivers 3dB of gain in a durable fibreglass construction with stainless steel hardware — built to withstand the UV exposure, salt spray, and vibration of the marine environment.\u003c\/p\u003e\u003cp\u003eCovering the full 156–163 MHz VHF marine band, it supports all standard marine VHF channels including Channel 16 (international distress and calling), weather channels, and working channels for vessel-to-vessel and vessel-to-shore communications.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: VHF whip antenna\u003c\/li\u003e\n\u003cli\u003eFrequency Range: 156–163 MHz (VHF marine band)\u003c\/li\u003e\n\u003cli\u003eGain: 3dB\u003c\/li\u003e\n\u003cli\u003eConstruction: Fibreglass with stainless steel hardware\u003c\/li\u003e\n\u003cli\u003eCompatible Systems: Furuno FM-4800 and FM-4900 series VHF radiotelephones\u003c\/li\u003e\n\u003cli\u003ePart Number: CX4-3\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e The CX4-3 is the correct replacement or upgrade antenna for Furuno FM-4800 and FM-4900 series VHF radiotelephones. It’s also a solid choice for any vessel running a Furuno VHF system where the original antenna has been damaged or degraded — a common issue on boats where the antenna has been exposed to years of UV and salt without replacement. VHF antenna condition directly affects communication range; a degraded antenna can cut your effective range significantly even if the radio itself is functioning normally. If you’re experiencing reduced range or poor audio quality on your VHF, replacing the antenna is the first and lowest-cost diagnostic step. Confirm your VHF radio model is compatible with the CX4-3 before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation Note:\u003c\/strong\u003e Mount as high as possible with a clear line of sight in all directions for maximum range. VHF is line-of-sight — antenna height is the single biggest factor in communication range. Use quality coaxial cable and weatherproof all connections.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eEstimated Packaging: Long box approximately 36\" × 4\" × 4\" (91 × 10 × 10 cm), approx. 0.7 kg shipped.
