TACTICAL

Members of military and law enforcement agencies around the world require communication capabilities in remote areas not serviced by traditional infrastructure. High frequency (HF) and very high frequency (VHF) radio overcome the challenges of operating in such locations, providing for transmission of voice, email, fax and data signals without relying on any supporting infrastructure.

Tactical HF and VHF radio are essential for members of military and law enforcement organisations that need to maintain communication to ensure operational success

What is HF radio?

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:

  • A transceiver with a microphone, speaker and frequency controls.
  • An antenna for broadcasting and receiving transmissions.
  • An independent power source.
What is VHF radio?

Operating in the band between 30 and 300 MHz, VHF radios are typically smaller, lighter and more portable than their HF counterparts. This makes them particularly useful for smaller units in the field communicating with one another.

VHF waves travel across the Earth's surface and do not reflect off the ionosphere. As such, they are limited to line-of-sight (LOS) transmissions - the antennas of the transmitting and receiving radios must be able to 'see' one another. Given this limitation, VHF is generally limited to ranges of approximately 8 kilometres. However, there are a number of solutions available for extending VHF propagation.
