MFJ-926 Remote Automatic Antenna Tuner

Introduction

The MFJ-926 Remote Automatic Antenna Tuner is designed to cover all frequencies ranging from 1.8-30
MHz. The multi-signal processing circuit switches inductance and capacitance as needed to match the
impedance of the antenna system with your radio. Fast tuning, less than 2 seconds after initial tuning.
Two-Hundred memory channels store the minimum SWR value to make tuning fast.
