MFJ 1:1 Current Balun
The MFJ 1:1 current balun is a device designed to enhance the performance of dipole antennas. It replaces the dipole's center insulator and consists of 50 ferrite core beads arranged on a 13-inch RG-303 coaxial cable. The device is then enclosed in schedule 40 PVC pipe to ensure maximum strength and protection. The connectors, including the coaxial and SO-239 connectors, are Teflon-coated to provide insulation and increase the product's durability. The MFJ 1:1 Current Balun is engineered to operate effectively in the 1.8-30 MHz frequency range, and it makes a direct electrical connection to the antenna with 14 AWG copper wire. By doing so, it can reduce or eliminate stray RF often found on coax, which can cause burns and other problems with electronic equipment. The reduction of stray RF increases the antenna's efficiency, resulting in an improved radiated power from the antenna and enhanced signal strength. If you are planning to construct your own dipole antenna, it is highly recommended to include the MFJ 1:1 Current Balun in your plans. Michael Brigmond MFJ Brand Manager GigaParts 04/05/2023
1:1 Current Balun
The 1:1 Current Balun was 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.
The coax and SO-239 connectors have Teflon(R) for maximum insulation and extended life of the product. The MFJ 1:1 Current Balun is enclosed in schedule 40 PVC pipe for maximum strength and protection. Unlike other baluns, the MFJ-918 makes a direct electrical connection to the antenna with #14 copper wire.
The MFJ Current Balun will reduce or eliminate stray RF often found on coax. This stray RF can cause burns and other problems with electronic equipment in ham-shacks and vehicles. Stray RF also results in a loss of radiated power from the antenna, which will lead to a great reduction in signal strength.
