2050 Wireless control HF Transceiver

wireless-set"The time and complexity to install HF transceivers into vehicles has been significantly reduced with the introduction 
of the Barrett 2050 Wireless control HF transceiver".

-Wireless handset with LCD display
-Wireless speaker
-Optional GPS receiver incorporated within the 2019 automatic tuning mobile antenna

The protocol between the handset, speaker and the HF transceiver RF module is

proprietary and not based on any current wireless protocols such as Bluetooth© and 802.11.
This protocol and the spread spectrum frequency selection are specifically designed to operate in high RF environments from HF through to VHF and UHF.

The handset can be removed from the vehicle by the authorised operator disabling the use of the HF transceiver when unattended. For fleet use a security tethering cord is supplied to avoid the unit being removed from the vehicle. The handset has internal batteries (not user replaceable to preclude easy removal) and is charged by the mounting cradle that comes in two parts enabling mounting on a dash top or a dash vertical face.

Following installation and on initial power up the HF transceiver RF module automatically 'pairs' the speaker and handset to itself with a unique security code. This ensures that if vehicles are operated in close proximity their respective wireless links do not interfere with each other.

No GPS antenna is visible on vehicle exterior when using the GPS receiver option fitted internally in the 2019 automatic tuning mobile antenna.
