Out of stock

The KRT2-19-25 is a 25 watt fixed base station designed for small airports, helipads, airlines, oil rigs, etc.

Developed and manufactured in South Africa by PJ Aviation, the base station employs the KRT2 transceiver module by TQ Systems (originally developed by Dittel Avionik). A high performance, wide band, linear amplifier increases the output carrier power from 5w to 25w.

Transmit/receive switching is automatic, requiring only a single antenna. In the event of a PA or antenna fault, the transmitter output is automatically reduced to 5w.

TRANSCEIVER FEATURES

• Full graphic TFT colour display allows easy use under all light conditions including bright sun light.
