Detailed description

The AC Antennas CELmar0-1 marine VHF antenna is a robust omnidirectional communication solution designed for demanding maritime environments. Made of stainless steel in steel gray, this 1-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 (160–250 MHz) and FM (88–108 MHz) frequencies. Unlike traditional fiberglass models like the brand’s CX4 series, the CELmar0 uses a metal whip offering excellent flexibility and minimal wind load for a weight of just 0.36 kg.

Radiofrequency performance

Engineered 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) below 1.5:1, ensuring excellent signal efficiency without power loss. Its nominal impedance is 50 ohms with vertical polarization. Note that unlike some specific models in the lineup, this antenna is not DC-shorted. Connection to the communication system is 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). IP66-certified for waterproofing against breaking waves, it remains fully operational across an industrial temperature range from -55 °C to +60 °C. The CELmar0-1 version ships with the N163F mounting bracket for immediate onboard integration. The antenna base uses a standard 5/8-inch thread with 24 threads per inch (TPI), ensuring a strong and durable mechanical attachment.

Expert opinion

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

The CELmar0-1 antenna from AC Antennas is a must-have standard for high-speed boats, rigid inflatables, and workboats requiring equipment with minimal windage. Its 1-meter stainless steel whip delivers superior mechanical resilience against impacts and vibrations, where a traditional fiberglass antenna could shatter. Withstanding winds up to 45 m/s (over 160 km/h) and IP66 certification, it is built for extreme maritime conditions. The fact that this version integrates the N163F mounting bracket with a standard 5/8" (24 TPI) thread makes installation particularly simple and robust. From a radiofrequency standpoint, its 3 dB marine gain and VSWR below 1.5:1 ensure optimal VHF range for an antenna of this size, while offering the highly practical versatility of receiving DAB and FM bands for onboard entertainment.

Frequently Asked Questions

Need help? Contact us

Is the mounting bracket included 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, absolutely. 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 corrosion resistance in a marine environment.

What type of connector is used on this antenna?

The antenna is fitted 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 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 rated for 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 on the 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 source a cable with a UHF-male (PL-259) connector 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).

Is the antenna DC-grounded (current continuous grounded)?

No, the technical specifications indicate that this antenna is not DC-shorted (DC-grounded: No).

What is the thread size at the base of the antenna?

The mounting thread is a standard 5/8 inch with 24 TPI (threads per inch), making it compatible with many market supports.

Is this antenna compatible with VHF radios from all brands?

Yes, this antenna is compatible with the vast majority of marine VHF radios on the market, as it uses a standard 50-ohm impedance and a female UHF connector. Simply use a suitable coaxial cable.
