Built Tough VHF Marine Repeaters Work!
Simple, Quick Setup & Go !
VHF Marine Repeaters are designed to provide coverage on Marine Repeater Channels as well as Crossband coverage for Land Mobiles and Land Based Stations. These systems are designed for use in Offshore Operations, for example, the Carrbean, South America, Central America, South Pacific, Africa and South East Asia, where the need for access to Extended Marine Communications and linked Marine to Land services are critical for effective safety.
Through the use of Marine Repeater Channels, a weak station would be amplified through the repeater and the signal re-transmitted to other stations on the same repeater channel. Additionally, through the built-in UHF linking, the signal could be accessed by Land Mobile Users or alternatively, connected to the local Landline Phone System enabling Marine mobiles access to the local PSTN network.
Our VHF Marine Repeaters are built on a highly configurable platform, using transceivers in modular form, that includes cross-connect modules, and a built-in VHF Duplexer utilizing a full 25 WATTS of output power.
We build different designs to suit your needs; Transportable & Stationary.
VHF Marine Repeaters increase the distance that Standard VHF Marine services can communicate through pre-programmed repeater channels that come standard with all Marine VHF radios. These channels include Duplex Channels 26, 27 & 28 in both International & USA Mode (See full list below).
Fully Portable Systems built inside an AMMOCAN box, or alternatively, a fixed station system, built inside a Communications Shelter; powered from Solar or Conventional A/C.
Bridge to Engine Room Communications
Often, workers in the Engine room need radio communications above-deck. Because of the thick steel between decks, this presents a real challenge. We build repeaters that help communications above and below deck through dual antenna systems and leaky feeder type configurations.
