Mfj-913 4:1 current balun 300w.


The MFJ-913 4:1 current balun is a versatile tool suitable for folded dipoles, delta loops, and other medium impedance balanced antennas. Whether you're an experienced ham radio operator or a beginner, the MFJ-913 offers reliability and efficiency in enhancing your HF radio experience.

MFJ 4:1 current baluns feature two large low-permeability ferrite cores and are designed to replace the centre insulator of a dipole antenna. The MFJ-913 is rated at 300 watts, while the MFJ-919 can handle up to 1500 watts. These baluns have SO-239 coax connectors with Teflon™ internal insulation, ensuring durability and maximum insulation. They make direct electrical connections to the antenna using #14 stranded copper wire and are enclosed in Schedule-40 PVC for robust support.

Key specifications of the MFJ-913 current balun include a 4:1 ratio, 50 Ohms impedance, frequency range of 3.5-30MHz, power handling capacity of 300W, SO-239 socket, eye bolt fasteners, compact dimensions of 45 x 93mm (body only), and a weight of 225g. Installing an MFJ-913 or MFJ-919 current balun can effectively reduce stray RF on coax, enhancing the efficiency and performance of any amateur radio station.
