Static communication infrastructure, such as landlines, mobile phones, LMR networks and fibre infrastructure, are easily disrupted and susceptible to failure through natural and manmade disasters. In some remote areas, this infrastructure simply doesn’t exist.
Organisations providing critical services need a form of communication that works without the need for any external supporting infrastructure. HF radio is an ideal solution, working as either a primary or emergency system for communication.
With an HF radio setup, organisations have everything they need in order to transmit voice, email, fax and data signals over long and short distances - a necessary capability in critical communications scenarios.
Barrett HF radios can provide critical communications capabilities for a number of public- and private-sector applications, including:
|Embassies and consulates||Energy|
|Post||Remote healthcare needs|
HF radio is a system of communication that operates on the portion of the radio spectrum between 1.6 and 30 megahertz (MHz). This form of propagation uses single side band (SSB) transmissions - an efficient form of voice modulation - to carry signals over both short and long distances.
There are two main forms of radio wave transmission in HF radio: ground and sky waves. Ground waves travel along the Earth's surface, enabling communication across short distances. Sky waves are bounced off the Earth's ionosphere in order to reach transmission ranges of several thousands of kilometres.
With these types of transmission, HF radio facilitates communication to and within isolated areas. A typical setup consists of three components:
This versatile 125 Watt transceiver features advanced digital selective calling systems and can be customised to meet customer specifications. Addressing the need for more intuitive operation, the 4050 SDR has fully automatic HF link set up protocols enabling the user to make calls direct from an address book and has full iOS, Android and MS smart device interfacing so the user can operate the HF radio from their PC, tablet or smart device.
Features rapid tune time of less than 1.5 seconds and are designed specifically for use with the Barrett 2000 and 4000 transceiver series. It features solid-state design for added durability.
Featuring a rapid tuning time of less than 1.5 seconds in typical usage, the 2019 automatic tuning mobile HF antenna works well with the Barrett Communications 2000 series of transceivers. It features solid-state design for added durability.
HF radio operators can use the 2060 automatic telephone interconnect to directly dial into and receive calls from the international phone network.
Bringing advanced broadcast capabilities to HF radio, the 2020 email systems enables email, fax and data transmission over HF radio waves.
For improved interoperability, the 2062 HF-VHF/UHF crossgate enables the automatic rebroadcasting of communications between HF and VHF/UHF systems.
Available in 500-watt or 1-kilowatt configurations, this high-power transmitter provides the broadcasting power required for base station operations.
