TG480-(025)-(20) [Part #0940.436-926]
The TG 460 series of ground stations offers a lowcost, stand-alone solution for ground to air voice communication (AM/A3E) in the VHF band for Air Traffic Control. This transceiver is ideal for airfields, small airports, oil rigs or as emergency station for main VHF systems.
The heart of the TG 460 is the Becker AR4201 transceiver which utilizes state of the art technology to cover the whole 118 MHz to 137 MHz frequency range, operating on all 760 channels. Preprogramming of 99 channel memories and scanning through the preprogrammed channels are standard features with the unit.
The unit is built as a compact 2U high rack mounting package, good for both desktop and rackmount applications. A simple operation is guaranteed from the key pad on the front panel and a 2-line LCD display clearly indicates the selected operational mode. The unit can be supplied with both AC and DC.
The TG 460 is available with 10, 20 and 50 W transmitter carrier power. The 50 W version works only with an external DC power supply.
Comprehensive BITE monitors the unit to ensure proper operation at all times and facilitate maintenance.
The transceiver can be remotely controlled via a multiwire cable up to 100m using a desktop remote control. For larger distances a 2-wire remote control interface is optionally available.
A tape recorder output and an RS232 port for remote management are standard with the unit.
A complete range of accessories is available for the system to operate in different applications.
