CX-UHF3-HL Marine UHF Antenna for Coastal Commercial Communications
The CX-UHF3-HL marine UHF antenna is designed for professional marine and land-based communication systems operating across crossover commercial UHF allocations. With 3 dBd gain, omnidirectional coverage, and a 220W power rating, it is well suited to coastal infrastructure, harbour support, vessel coordination, utility communications, and mixed marine/land RF networks.
This antenna is particularly useful where operators require reliable communication between vessels, shore stations, port infrastructure, coastal utility sites, and commercial field units operating across the 455–500 MHz frequency range.
Coastal Commercial RF Installation
The CX-UHF3-HL is positioned for coastal commercial RF systems where reliable communication is required between workboats, harbour support vessels, shore base stations, utility sites, and coastal operations teams.
Its crossover frequency range supports practical marine and land-based communication networks where vessels and shore infrastructure must operate together across demanding coastal environments.
455–500 MHz Commercial UHF Allocation
The CX-UHF3-HL supports multiple frequency options across the 455–500 MHz commercial UHF range. This makes it useful for RF planning where coastal coverage, commercial allocation, channel spacing, licensing, and site-specific communication requirements must be considered.
Coastal Utility & Harbour Coordination Network
Coastal communication networks often involve both marine and land-based users. The CX-UHF3-HL supports this type of mixed RF architecture by providing balanced omnidirectional UHF coverage for vessels, shore facilities, utility sites, field teams, emergency services, harbour operators, and logistics support networks.
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.
