MFJ-915 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.
|The MFJ-915 RF Isolator is a 1:1 Current Balun / Common mode filter designed to be placed in line with a 50-Ohm coax. The RF Isolator is effective from 1.8 to 30 MHz. CM|| : ||> -35 dB / 15 MHz|
It is made up of 50 Ferrite Core Beads, placed onto a 13-inch piece of RG-303 coax. The coax and SO-239 connectors have Teflon(R) for maximum insulation and extended life of the product.
