1.26m Marine VHF Antenna

The length of this marine VHF antenna is 1.26 meters (4.1 feet).

The antenna weighs 0.38 kg (0.84 lbs), making it lightweight and easy to install.

This antenna can support a maximum transmit power of 100 watts.

The antenna gain is 3 dB (equivalent to 0 dBd).

The antenna is designed for maximum durability at sea. It is made of:

A fiberglass whip.
A white polyurethane varnish coating that protects it from UV rays and salt air.

Yes, this antenna has an IP66 protection rating, meaning it is fully protected against dust and powerful water jets from any direction.

It is designed to operate in extreme conditions, with an operating temperature range from -55 °C to +60 °C.

The antenna has been tested to withstand winds up to 45 m/s, which is equivalent to 162 km/h.

Yes, the antenna features a continuously short-circuited design (DC-shorted). This characteristic effectively protects your radio equipment against electrostatic discharges.

This antenna is designed for the marine VHF band and operates over a frequency range of 149.0 to 162.5 MHz.

Thanks to its compact size of 1.26 m, the CELMAR1-1 antenna is ideal for sailboats, motorboats, and workboats where mast or roof space is limited.

The Voltage Standing Wave Ratio (VSWR or TOS in French) is maintained at a value below 1.5:1 across the entire frequency band, ensuring excellent transmission efficiency.

The antenna is equipped with a standard UHF female connector at its base, making it easy to integrate with most marine mounts.

This antenna has vertical polarization. For optimal performance, it must be installed in a perfectly vertical position, ideally as high as possible and away from any metal obstructions.

Yes, its base with a female UHF connector is a standard in nautical applications, making it compatible with most marine VHF antenna mounts (mast mounts, balcony mounts, swivel mounts, etc.).

No, the coaxial cable and mounting brackets are not included with the antenna. You must purchase a 50-ohm cable and a suitable mount separately.

Yes, this antenna is compatible with nearly all marine VHF radios on the market because it uses a standard 50-ohm impedance and a female UHF connector, which are the norms in the maritime sector.

Yes, absolutely. The antenna’s frequency range (149.0–162.5 MHz) fully covers the frequencies used by AIS systems (161.975 MHz and 162.025 MHz). It is therefore perfectly suited for use with an AIS receiver, transmitter, or transponder.

To connect this antenna, you will need a coaxial cable with a 50-ohm impedance (e.g., RG-58 or RG-213). The cable must be fitted with a PL-259 (male) connector to screw onto the antenna’s female UHF base.

Yes, a nominal 50-ohm impedance is the universal standard for all marine VHF radios and associated coaxial cables. Compatibility is therefore ensured with equipment that meets this standard.
