Full Duplex Radio Systems

Conventional two way radios provide simplex (or half duplex) communication. The PTT button is used to talk then released to listen so you can therefore only talk or listen at any one point of a conversation.

Full duplex radio equipment provides the functionality of two way conversations which allows users to talk and listen naturally, as you would on a telephone conversation, with out the use of a PTT.

We can provide various options, with a number being for specialised usage, for example in tower cranes.

Please contact us for further information.
