Static communication infrastructure, such as landlines, mobile phones and fibre infrastructure, can be disrupted through natural and manmade disasters.
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:
| Agriculture | Construction |
| Embassies and consulates | Energy |
| Emergency services | Fisheries |
| Forestry | Mining |
| Post | Remote healthcare needs |
| Shipping | Telecommunications |
| Transportation |
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.
Providing a frequency coverage of 1.5 to 30 MHz, the Barrett 4049 (P/N: BC404901 Black) features rapid tuning (typically less than 1.5 s) and low power consumption capabilities.
The active tuning elements of the antenna are housed in a waterproof, high-impact resistant moulding. This housing incorporates a heavy duty anti-vibration mount at its base.
The development of the HF Radio Mailbox is based on the increasing demand for users to be able to communicate from wherever they are, including isolated locations connected only by HF radio, using the existing email client i.e. Outlook on their personal device, be it a smartphone, tablet or laptop, in much the same way as they can use the WiFi in their own office.
Monitoring the position of mobile assets is critical to their effective management in both marine and land mobile environments. The Barrett 4077 HF Map & Track solution provides situational awareness for commercial, non-government and government agencies alike, including fishing fleets, long distance haulage, emergency response including police and defence force deployments.
Available in 500-watt or 1-kilowatt configurations, this high-power transmitter provides the broadcasting power required for base station operations.
The Barrett 2064 Radio Voice Bridge has been designed specifically to monitor and bridge two different types of radio network simultaneously whether they be HF, VHF or UHF. Through a H250 handset, a user can monitor the audio from both networks. The user can select the individual network through which to talk whilst still being able to monitor activity on the other network via LED indicators on top of the unit.
HF radio operators can use the 2060 automatic telephone interconnect to directly dial into and receive calls from the international phone network.
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.
