CX-UHF3-HH-A Marine UHF Antenna for 480–510 MHz Communications
The CX-UHF3-HH-A marine UHF antenna is designed for professional marine and land-based communication systems operating in the higher commercial UHF band. With 3 dBd gain, omnidirectional coverage, 220W power handling, and an included N275F mount, it is well suited to port operations, industrial harbour communications, vessel coordination, utility sites, and offshore support networks.
This antenna package is particularly useful where operators require dependable UHF coverage between vessels, shore stations, port infrastructure, and commercial fleet units.
What Does the CX-UHF3-HH-A Version Include?
The CX-UHF3-HH-A version is supplied complete with the AC Antennas N275F marine mounting bracket. This provides a ready-to-install commercial UHF antenna package for marine and industrial RF infrastructure projects where secure mast or rail mounting is required.
The included N275F mount helps reduce specification time by supplying the antenna and primary mounting hardware together as one package.
Supplied with AC Antennas N275F Marine Mount
The CX-UHF3-HH-A is supplied with the AC Antennas N275F mount for secure installation on suitable marine structures, harbour infrastructure, offshore support craft, utility installations, and industrial RF sites.
This makes the CX-UHF3-HH-A a practical option for professional installers who require a matched UHF antenna and mounting solution for commercial marine communications.
Industrial Harbour RF Infrastructure Installation
The CX-UHF3-HH-A is positioned for industrial harbour RF systems where reliable communication is required between port authority teams, tug crews, pilot boats, cargo operations, maintenance vessels, and shore-side communication infrastructure.
Its higher-frequency operating range makes it suitable for commercial UHF networks used in busy ports, logistics environments, utility operations, and industrial marine sites.
480–510 MHz Commercial UHF Spectrum
The CX-UHF3-HH-A operates across the 480–510 MHz range. This makes it suitable for professional RF planning where frequency allocation, licensing, channel availability, interference management, and site-specific installation conditions must be considered.
Port Operations & Vessel Coordination Systems
Commercial harbour communication networks rely on clear coordination between shore control, port services, tugs, pilots, terminal operators, and vessels operating inside controlled waterways. The CX-UHF3-HH-A supports this type of operational RF architecture by providing balanced 3 dBd omnidirectional UHF coverage for marine and land-based users.
Professional Marine RF Installation
Correct antenna positioning remains important for reliable UHF performance. The antenna should be mounted with clear line of sight where practical and kept suitably separated from radar scanners, satellite domes, navigation antennas, high-power transmitters, and major RF noise sources.

CX-UHF3-HH-A FAQ
What frequency range does the CX-UHF3-HH-A cover?
The CX-UHF3-HH-A is specified for 480–510 MHz commercial UHF communications.
What does the “-A” version include?
The “-A” version is supplied with the AC Antennas N275F marine mounting bracket, making it a matched antenna and mount package.
Is the CX-UHF3-HH-A suitable for harbour communications?
Yes. It is suitable for harbour coordination, port communications, vessel traffic support, utility operations, and industrial marine UHF networks where the assigned operating frequency is within the antenna range.
Can the CX-UHF3-HH-A be used on land-based RF systems?
Yes. The antenna is suitable for both marine and land-based commercial UHF systems, provided the installation and frequency allocation are appropriate.
What cable should be used with a UHF marine antenna?
Cable choice depends on installation length and acceptable signal loss. For longer UHF cable runs, lower-loss coaxial cable such as RG213/U or RG214/U is often preferred over smaller RG58 installations.
