The MFJ-941E antenna tuner is an automatic antenna tuner designed to work on frequencies from 1.8 to 30 MHz. Its main function is to match the antenna impedance to 50 ohms to achieve optimum power transfer between the radio and the antenna. The MFJ-941E is designed to adapt virtually any transmitter to any antenna, including dipoles, invertedvees, verticals, mobile antennas, beams, random wires, and other antennas fed by coaxial lines, balanced lines, or a single cable. An eight position antenna selector switch provides versatile antenna selection. The MFJ-941E can handle up to 300 watts of RF output power from the transmitter. The MFJ-941E uses a cross-needle meter to simultaneously read forward power, reflected power, and SWR.
The maximum power that the MFJ-941E can handle is 300 watts of Peak Surround Power (PEP). This means that it can handle high-power signals transmitted in SSB (Single Sideband) mode and other transmission modes that use peak envelope power as a reference.
The MFJ-941E antenna tuner is very useful for adjusting and optimizing antenna efficiency in a wide range of HF (high frequency) frequencies. This allows better transmission and reception of signals in bands such as 80 meters, 40 meters, 20 meters, 15 meters and 10 meters, among others.
Remember that it is important to follow the manufacturer's instructions for the proper use of the antenna coupler and to ensure that the transmission power does not exceed the maximum limit of 300 W PEP to avoid damage to the equipment.
Wide frequency range: The MFJ-941E is designed to work in the frequency range of 1.8 to 30 MHz, which covers the most common HF bands. 50 ohm impedance: This coupler is responsible for matching the impedance of the antenna at 50 ohms, which is the standard used in most amateur radio equipment. 300 W PEP Peak Power: The MFJ-941E can handle up to 300 watts of Peak Envelope Power (PEP), allowing it to withstand high-power signals transmitted in different modes. Automatic Matching: This tuner features an automatic mechanism that automatically adjusts the impedance of the antenna to achieve optimal power transfer. Measurement Display: The MFJ-941E is equipped with a display that shows relevant information such as transmit power and antenna impedance status, making it easy to monitor and adjust. Connectors and Controls: The tuner has antenna and radio connectors for easy connection, as well as adjustment knobs to control impedance and output power. Compact and Durable Design: The MFJ-941E is designed compactly, making it convenient for installation in ham stations with limited space. In addition, it is built with durable materials that guarantee its reliability and resistance in the long term.
