Marine CB radios are compact communication devices used for short-range maritime communication. They operate on specific frequencies to ensure clear and reliable contact between vessels. These systems are essential for safety, coordination, and emergency situations at sea.

Marine CB Radios typically operate on the 27 MHz band with 40 channels. They have a power output of 4-6 watts for AM and 12 watts for SSB. Size ranges from compact handheld units (6x3x1.5 inches) to larger fixed-mount models (8x5x2 inches). Grade is usually IPX7 or higher for waterproofing. Viscosity and buoyancy are not applicable. Materials include ABS plastic, rubberized coatings, and corrosion-resistant metals.

Marine Communication Systems (VHF) operate on 156-174 MHz with 25-50 watts power output. Size varies from handheld (7x2x1.5 inches) to fixed-mount (10x6x3 inches). Grade is IPX8 for submersion resistance. Buoyancy is optional with floating designs. Materials include polycarbonate, stainless steel, and waterproof seals. Viscosity is not applicable.

Antennas for marine radios are typically fiberglass or stainless steel, 3-8 feet in length, with a base diameter of 1-2 inches. They are UV-resistant and corrosion-proof. Buoyancy is not applicable unless designed as a floating antenna.

Coaxial cables are RG-8X or RG-58, with a diameter of 0.25-0.5 inches, made of copper core and PE insulation. Viscosity and buoyancy are not applicable.

Batteries for handheld units are Li-ion or NiMH, 7.4V-12V, with capacities of 1500-3000 mAh. Materials include lithium compounds and plastic casings. Buoyancy is not applicable.
