- Page 2 - 1 - Introduction: The AT-11MP is a full-featured auto or semi automatic antenna tuner designed for HF (1.8 to 30 MHz) transceivers using between 5 to 150 watts. The tuner uses a switched “L” configuration with 256 capacitor, 256 inductor and Hi/Lo-Z settings to provide over one hundred and thirty thousand tuning combinations.
- Page 3 Power and ground must still be provided through the AT-11 MP coaxial power jack. Also be sure to power the AT-11MP on first, then the radio to allow the radio to know that a remote tuner is present.
- Page 4 A 40-meter dipole (at 30 feet) would tune just about anywhere from 3.1 to 30 MHz! We had some problems at 19 and 28 MHz finding a 1.5 match. The AT-11MP usually found a 2.0, and then we had to use the manual switches to get below 1.5.
