Aviation Radio

Since the beginning, aviation and radio have gone hand in hand. At altitude, there has always been a need for efficient and rapid communication, which is most easily achieved by this technique. Nowadays, clear standards and modern tools are available to help professional and amateur pilots and ground crews. Also known as re-band radios, they can do much more than just provide two-way communication.


Airborne frequencies are of the AM, or amplitude modulation, type. The high-frequency wave (VHF) is specifically suited for long-distance and high-altitude communications. Some 760 channels are used in airborne communications today, separated by 25 kHz steps. Naturally, each channel and frequency has a different purpose: navigation, communication or distance measurement.

Aeronautical frequencies

108.000 - 136.975 MHz

The full rep band used in civil aviation, including small and large aircraft, business and private traffic.

108,000 - 117,975 MHz

The civil aviation range for navigation purposes (NAV).

118,000 - 136,975 MHz

The COM, or communications range for civil aircraft.

Military frequencies

The frequencies used by the armed forces are located above the civilian frequencies. These frequencies are typically secret and civilian radios are not able to receive these ranges.

121.5 MHz

International emergency frequency. Search teams use the radio signals transmitted on this frequency to locate a distressed aircraft. Accordingly, it is only to be used in case of emergency. Some radio repeaters can be set to transmit automatically to ensure that the distress signal is broadcast continuously.

255 - 495 kHz

Frequency of the route direction finder (NDB). Not to be used for verbal communication.

108 - 111,975 MHz

Instrument Landing System Direction Finding (ILS LOC). Not to be used for verbal communication.

What should be considered when buying an airband radio?

Portability

We offer a range of handheld, desktop, car and small aircraft radios. All of these types require a radio licence to be used as a radio transceiver (our company will be happy to help you obtain a licence). The desktop ground-to-air radios are ideal for installation in control panels or in vehicles due to their external antenna connection. Hand-held radios are typically available with display and in full pocket design.

Ease of use

Modern radios are not particularly complicated to use and offer a range of convenience features to help users. Most models allow hundreds of channels to be stored and wireless headphones can be connected via Bluetooth. Large displays make it easy to keep track of key information, and advanced Li-Ion batteries allow for extremely long battery life.

Extra features

Before you decide, you should also consider what extra features you need. These could include a slim design or intercom functions. The built-in GPS is a very useful addition for any aircraft, as is the VOR function, which also plays a role in positioning. The active noise reduction available in some models and the increased speaker power allow even more precise communication.
