MFJ-934 Combined Artificial Earth & Antenna Tuner (ATU) is a versatile unit that integrates the functionalities of the MFJ-931 artificial earth and the MFJ-941 antenna tuner. Designed to accommodate a wide range of applications, it effectively matches coax feeders, balanced wires, and end-fed wires, making it an ideal solution for amateur radio operators facing challenges with grounding or RF live chassis. With a frequency range of 1.8- 30 MHz and a power handling capacity of up to 300 W, this unit is well-suited for various operational needs.
One of the standout features of the MFJ-934 is its cross-needle meter, which simplifies the tuning process by providing clear visual feedback on the matching status. The meter displays both VSWR and power levels (30w and 300w), enabling users to optimise their antenna systems efficiently. Additionally, the unit includes a 3-way antenna selector, illuminated meter for easy visibility in low-light conditions, and tuning and reactance controls that allow for precise adjustments. The internal 4:1 balun further enhances its versatility, accommodating different antenna configurations.
