Detailed description

The CELmar0-1 marine VHF antenna from AC Antennas is a robust omnidirectional communication solution designed for demanding maritime environments. Made of stainless steel in a steel-gray color, this one-meter antenna stands out for its reliability and ability to maintain clear communications on the marine VHF band (156.0–162.5 MHz), while also covering DAB frequencies (160–250 MHz) and FM (88–108 MHz). Unlike traditional fiberglass models such as the CX4 series from the same brand, the CELmar0 features a metal whip offering excellent flexibility and minimal wind load for a weight of just 0.36 kg.

Radiofrequency performance

Designed for optimal transmission, the CELmar0-1 operates at a nominal power of 100 watts. It delivers a marine gain of 3 dB (0 dBd) and a Voltage Standing Wave Ratio (VSWR) of less than 1.5:1, ensuring excellent signal efficiency without power loss. Its nominal impedance is 50 ohms with vertical polarization. Note that unlike certain specific models in the range, this antenna is not DC-shorted. Connection to the communication system is made via a standard female UHF socket.

Mechanical design and installation

Built to withstand harsh offshore conditions, this antenna resists extreme winds up to 45 m/s (101 mph). Certified to IP66 for waterproofing against breaking waves, it remains fully operational across an industrial temperature range from -55 °C to +60 °C. The CELmar0-1 version is supplied with the N163F mounting bracket, enabling immediate integration on board. The antenna base uses a standard 5/8-inch thread with 24 threads per inch (TPI), ensuring a strong and durable mechanical attachment.

Important: coaxial cable and connectors required for antenna connection are not included.

Expert opinion

« Extreme mechanical durability and VHF/FM versatility for high-speed vessels »

The CELmar0-1 antenna from AC Antennas is a standard fixture for high-speed boats, rigid inflatables, and workboats requiring an antenna with very low windage. Its 1-meter stainless steel whip delivers superior mechanical resilience against impacts and vibrations, where a traditional fiberglass antenna could fracture. Withstanding winds of 45 m/s (over 160 km/h) and IP66 certification, it is built for extreme maritime conditions. The integrated N163F mounting bracket with a standard 5/8" (24 TPI) thread simplifies installation while ensuring robustness. In terms of radio frequency, its 3 dB marine gain and VSWR under 1.5:1 guarantee optimal VHF range for an antenna of this size, while also offering the added versatility of receiving DAB and FM bands for onboard entertainment.

Frequently Asked Questions

Need help? Contact us

Is the mounting bracket supplied with the antenna?

Yes, the AC-CELMAR0-1 version is supplied with the N163F mounting bracket included, which makes installation straightforward upon receipt.

Is this antenna compatible with AIS receivers?

Yes, exactly. The frequencies used by AIS systems (161.975 MHz and 162.025 MHz) fall within the marine VHF frequency band (156.0–162.5 MHz) covered by this antenna.

What material is the antenna made of?

The antenna is made of stainless steel, providing high robustness and excellent resistance to corrosion in marine environments.

What type of connector is used on this antenna?

The antenna is equipped with a standard UHF female connector (also known as SO-239).

Can I also receive FM radio with this antenna?

Yes, this antenna is designed to receive the FM frequency band (88–108 MHz) and digital radio DAB (160–250 MHz) in addition to marine VHF.

What is the weight of the antenna alone?

The antenna weighs 0.36 kg (or 0.8 lbs), making it lightweight and minimizing load on its mounting point.

Is this antenna waterproof?

Yes, this antenna has an IP66 protection rating. It is fully protected against dust and powerful water jets, including breaking waves.

What is the maximum power this antenna can handle?

This antenna is designed to handle a maximum transmit power of 100 watts.

What is the impedance of this antenna?

The nominal impedance of the antenna is 50 ohms, which is the standard for marine VHF radio equipment and ensures maximum compatibility.

What is the gain of the CELmar0-1 antenna?

The gain of this antenna is 3 dB in marine scale, which is equivalent to 0 dBd.

Is a coaxial cable included with the antenna?

No, the AC-CELMAR0-1 version includes the antenna and its N163F mounting bracket, but the coaxial cable is not supplied. You will need to purchase a cable with a UHF male connector (PL-259) to connect it to your radio.

What is the wind resistance of this model?

This antenna is designed to withstand winds up to 45 m/s, approximately 162 km/h (101 mph).
