MFJ-918 - 1:1 ratio 50-Ohm, 1.8-30 MHz, 1.5 kW current balun designed to minimize losses and deliver superior suppression over the entire HF range.
This is designed to replace the feed-point insulator on wire antennas and provide balun protection. Rugged stainless steel eye bolts provide the superior pull-strength needed to support a full-sized 160-Meter dipole, and the top eye-bolt accepts a center-support halyard to reduce wire strain. Two #14 stranded copper-wire pigtails solder directly to the antenna wire for reliable conductivity. On the inside, high-permeability ferrite beads are installed over RG-303 Teflon coax to ensure high power handling, maximum suppression, and minimal signal loss. Thick-wall chemically welded PVC construction guarantees long life under adverse environmental conditions, and a high-quality Teflon-insulated SO-239 at the base provides a secure connection for your coax.
