MFJ-918 1:1 Current Balun
The 1:1 Current Balun is designed to replace the center insulator of a dipole antenna. It is made up of 50 Ferrite Core Beads placed onto a 13-inch piece of RG-303 Coax. Operates 1.8 to 30 MHz.
Features a SO-239 connector with Teflon(R) for maximum insulation and extended life of the product. The MFJ-918 1:1 Current Balun is enclosed in schedule 40 PVC pipe for maximum strength and protection from the elements. Unlike other baluns, the MFJ-918 makes a direct electrical connection to the antenna with #14 copper wire.
