With the MFJ-862, you have complete control over power measurements with its front panel rotary switch, allowing you to choose between two power scales for each band. The low-power scale ranges from 0-30 watts forward and 0-6 watts reflected, while the high-power scale covers 0-300 watts forward and 0-60 watts reflected. Regardless of your power requirements, this meter has got you covered.
The MFJ-862 operates based on a sophisticated theory of operation. It utilizes a 50-ohm stripline that senses RF energy, with forward and reflected striplines coupling to create a highly efficient directional coupler. This unique design allows the meter to accurately detect current and voltage along the 50-ohm stripline, generating proportional voltage signals. These signals are rectified by a diode and then smoothed by a capacitor, resulting in precise power measurements.
When it comes to connectivity, the MFJ-862 offers simplicity and versatility. Connect your transmitter to the dedicated TRANSMITTER input and your antenna to the ANTENNA connector. It is essential to use high-quality coaxial cables and connectors specifically designed for VHF/UHF frequencies to ensure optimal performance.
Whether you’re a seasoned ham radio operator or just starting out, the MFJ-862 VHF/UHF Cross-Needle Meter is an indispensable tool for accurate power measurements and SWR monitoring. Take your radio operation to the next level with this reliable and feature-packed meter.
