Two Way Radios and Cars

Mobile radios fitted in cars require little maintenance if the radio and antenna are permanently installed. However our engineers find that in lots of cases when the radio is fitted in hire cars the radio/antenna has to be easily removable. This results in the use of magnetic mounted antenna and the radio fitted under one of the front seats. Because the wiring is not fixed it is likely to get damage and become unreliable.

The two main areas that cause the most problems are that aerial cable and the microphone cable. Damage to the aerial cable will reduce the coverage area, put excessive strain on the electronics of the radio and area of radio coverage becomes unreliable. If the cable is not repaired or replaced expensive repairs to the mobile may be also required. Unfortunately as the aerial cable is coaxial it is not simply a case of a visual inspection but needs to tested with calibrated test equipment.

Damage to the microphone cable is also hard to detect as the cable is made up of very thin flexible wire, if it is damaged it will result is intermittent communication until it fails completely.

Some customers have obtained magnetic antennas that have a small magnetic base and very thin aerial cable (coax) believing that this will solve problems with the area of coverage - wrong! an antenna that is used for two way communication needs to be adjusted to operate on the required frequency efficiently.

The magnetic base is too small to keep the antenna on the roof of cars when passing under such things height restriction bars in car parks. Two-way radios and base stations should be checked at lest once a year to ensure that the equipment is operating within manufactures specifications and licensing requirements.

The Phonetic Alphabet

The Phonetic Alphabet is used by radio operators, to spell out words. It is useful when exchanging important and precize information (addresses, names, etc) especially during not clear transmission. This alphabet has been changed over the years and in different groups of radio users and different countries the alphabet varying from each other.

The NATO phonetic alphabet, more formally the international radiotelephony spelling alphabet, is the most widely used spelling alphabet. Though often called "phonetic alphabets", spelling alphabets have no connection to phonetic transcription systems like the International Phonetic Alphabet.

Instead, the NATO alphabet assigns code words to the letters of the English alphabet acrophonically so that critical combinations of letters (and numbers) can be pronounced and understood by those who transmit and receive voice messages by radio or telephone regardless of their native language, especially when the safety of navigation or persons is essential. The paramount reason is to ensure intelligibility of voice signals over radio links.

We have a list of the phonetic alphabet on our website that lists the words from NATO & International Aviation, British Forces, NY Police, French, German, Italian and Spanish!

Tour of Britain


Communication Specialists provide two way radio for the Tour of Britain



The Tour of Britain is a blue riband cycling event that returned to the British cycling calendar in 2004 after an absence of five years. Cycling is a hugely popular sport and British cyclists are among the best in the world, winning five gold medals in the 2004 Olympics and Paralympics.

The Tour of Britain has formerly been known as the Milk Race, the Kellogg's Tour and the Pru Tour of Britain. The aspiration of the Tour of Britain was to re-launch the event along the lines of the Tour de France, which has no title sponsor but a spectrum of public and private sector support.

The Tour of Britain has placed itself on a global platform alongside major races such as The Tour de France and Giro d'Italia by attracting a combination of national and international teams. Teams which are attracted to racing the Tour of Britain include Pro Tour Teams such as T-Mobile, Quickstep, Phonak and CSC.

The world governing body the UCI (the Union Cyclisme Internationale) granted the 2004Tour of Britain world championship ranking status. The Tour of Britain is determined in the future to become part of the UCI's elite Pro Tour calendar.

The Tour of Britain has four founding directors: Chief Executive, Hugh Roberts who also heads sporting marketing and events company Sweetspot Tony Doyle MBE, twice world pursuit champion Mick Bennett, double Olympic medallist Peter Moore OBE, former Managing Director of Center Parc.

The Tour of Britain is a not for profit organisation governed by a Board of Trustees with representatives from the sport of cycling, trade and industry and politics.

Communication Specialists are sponsors of the Tour of Britain and installed their radio equipment, their engineers Slawosz Uznanski, Raymoond Brooks and Maciej Korneluk were there that day to help install the required equipment on Thursday 6 September 2007.

For the Tour of Britain Communication Specialists supplied the following equipment:

  • 4 mobile units GM950 for motorcycles with autocom headset systems
  • 80 + 30 hand portable Motorola radios with spare batteries and chargers

All systems work with 2 independent repeaters, located in the organisers cars, one in front of the cyclists group other one in the middle, to provide maximum coverage for all radio users.

Installation of car/mobile units was made on Thursday 6 September and Friday 7 September (motorcycles on Saturday).
