MFJ 1:1 Current Baluns
MFJ 1:1 Current Baluns were designed to replace the center insulator of a dipole antenna and are made up of 50 Ferrite Core Beads placed onto a 13-inch piece of RG-303 Coax and enclosed in schedule 40 PVC pipe for maximum strength and protection. The coax and SO-239 connectors are Teflon coated to extend the life of the product and provide insulation. The MFJ 1:1 Current Balun is designed to operate in the 1.8-30 MHz frequency range and makes a direct electrical connection to the antenna with 14 AWG copper wire and will reduce or eliminate stray RF often found on coax increasing the efficiency of the antenna. This stray RF can cause burns and other problems with electronic equipment resulting in a loss of radiated power from the antenna and reducing signal strength. Are you looking to build your own dipole antenna? Be sure to include one of these MFJ 1:1 Current Baluns in your plans!
