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 for maximum insulation and extended
life of the product.
This 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-918 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.
