Diamond FDV-11

The Diamond FDV-11 is a robust folded dipole antenna specifically designed for the VHF frequency range of 138 to 174 MHz . This professional wideband antenna combines a compact design with excellent performance – perfect for situations where reliability and a wide frequency range are essential.

With a gain of 1 to 2.5 dB, a maximum transmit power of 500 watts, and a low SWR (<1.5) , the FDV-11 guarantees stable, noise-free signal transmission. Whether you're working in traffic communications, maritime applications, BOS systems, or data transmission , this antenna always delivers consistent performance.

With its N-male connector , wind resistance up to 70 m/s , and a sturdy mast mount for diameters ranging from 30 to 62 mm , the FDV-11 is built for long-term use in demanding environments. The antenna is also fully weatherproof and comes with mounting hardware – ready for immediate installation.

Ideal for:

• Radio connections between mobile and fixed stations
• Maritime communication and inland navigation
• Operational traffic (railways, emergency services)
• Data transfer and telemetry systems
• Professional BOS and corporate communications

Looking for a reliable, powerful, and easy-to-install VHF antenna? The Diamond FDV-11 is ready for you.

Professional broadband antennas with omnidirectional coverage and impressive performance

The FDV and FDU series from the renowned Japanese brand Diamond consists of high-quality broadband loop dipole antennas, specifically developed for demanding professional radio communications. These antennas are designed for reliable, interference-free operation with an omnidirectional radiation pattern – ideal for applications requiring consistent, circular coverage around the transmitter.

The FDV series covers the entire VHF range from 138 to 174 MHz, while the FDU series covers the UHF spectrum from 406 to 512 MHz. Thanks to these wide, uninterrupted frequency ranges, both series offer an excellent solution for a wide range of communication applications.

Efficient, expandable and powerful up to 500 watts

These antennas are not only robust and reliable, but also expandable. By stacking multiple antennas of the same type (for example, two or four at a time), you not only increase gain and range, but also voice quality, data transmission reliability, and intelligibility in critical situations.

The antennas are easily mounted on a mast (mast diameter 33-62 mm) using a sturdy horizontal boom with the included mounting brackets. By adjusting the distance from the mast, you can also create a slight directionality – ideal for when you want extra control over the coverage area.
