This is an exciting new design which is made in the UK by Linear Amp UK. It is a true balanced, inductively coupled ATU covering the full HF spectrum from 160m to 10m. Rated at 1.5kW it is ideally suited for use with power well over the UK limit. This is a rugged design with over-rated components for long life and reliability. The unit can be used to feed balanced feeder, coax fed systems or long wires. Two versions LA-STWM with VSWR meter and LA-STNM without.

There are two sets of terminals on the rear of the unit, one covering 10m to 20m and the other 30m to 160m. It is possible to have separate antennas continually connected to each terminal set, thus avoiding the need for an antenna switch. For coax or end fed wires, you simply need to earth one of the terminals and connect the wire or inner of the coax to the other terminal.

The unit requires the connection to 12V at all times of operation as this is used to control relays that switch inductors from band to band.
