Voice Radio Antennas
TE Connectivity offers antennas for special and public communications like TETRA and CB radio.
Capabilities of Antennas for Voice Radio
- Passive antenna structure to support multiple bands
- Integrated or external solutions
- Well-defined RF interface to connect to state-of-the-art modems
- Customer-specific adaptations possible
- Combinations with other services feasible
Secure Speech and Data Transmission
Terrestrial Trunked Radio (TETRA) is a digital radio technology which resembles mobile phone networks. TETRA is the standard for digital trunked radio in the frequency range of 380 to 470 MHz.
As a fully digital system, it is characterised by its high transmission quality and better frequency economy in comparison with conventional mobile radio standards. It can transmit large volumes of data as well as speech and therefore optimally uses the capacity of the radio channel.
The standard is particularly suitable for public sector authorities and organisations, such as the police force, fire service and ambulance service, whose communication requires a secure network. However, TETRA antennas are also used by private organisations, such as cash transport companies, as well as in the field of airport communications.
Truck Communication, Reliable and Powerful
Citizen Band (CB) radio is a personal voice radio service which operates free of charge in unlicensed frequency bands. CB radio antennas are used for communication purposes in commercial vehicles such as trucks or special vehicles. They are developed in line with customer requirements and are available as external antennas or integratable solutions such as film antennas for exterior truck mirrors. Integrated varient provides reduced cw value, and does not affect vehicle design.
