Marine VHF radio antennas are essential for reliable communication at sea, designed to withstand harsh marine environments. They operate on VHF frequencies (156-174 MHz) to facilitate ship-to-ship and ship-to-shore communication. Proper antenna selection and installation ensure clear, long-range transmissions for safety and navigation.

Marine VHF Radio Antennas are typically designed with the following specifications and technical properties:

Size: Ranges from 3 feet (1 meter) to 8 feet (2.4 meters) in length, depending on application.

Grade: Marine-grade, corrosion-resistant materials meeting IPX6/IPX7 waterproof standards.

Viscosity: Not applicable (N/A) for antennas.

Buoyancy: N/A (antennas are mounted on vessels, not submerged).

Material: Fiberglass, stainless steel, or copper for durability and signal efficiency.

Frequency Range: 156-174 MHz (VHF Marine Band).

Gain: 3 dB to 6 dB for optimal signal transmission.

Impedance: 50 ohms standard.

Mounting: Stainless steel or aluminum base for secure installation.

Connector Type: PL-259 or N-type connectors.

Operating Temperature: -30°C to +70°C (-22°F to +158°F).

Radiation Pattern: Omnidirectional for 360° coverage.

Coaxial Cable: RG-8X or RG-213 for low signal loss.

Compliance: Meets FCC, CE, and ITU maritime regulations.

Yes, Marine VHF Radio Antennas and Marine Communication products typically comply with maritime standards such as ITU-R M.493, ITU-R M.541, and IEC 60945 to ensure safety and performance at sea.
