MFJ-915  RF ISOLATOR, 1.8-30MHZ, 1500W PEP

The MFJ-915 RF Isolator is a 1:1 current balun designed to be placed in line with a 50-Ohm coax. The RF Isolator is effective from 1.8 to 30 MHz. It was designed to improve the performance of all amateur stations, fixed or mobile.

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. Use of the MFJ-915 will increase the efficiency of all amateur stations.

Its 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. The RF Isolator is enclosed in schedule 40 PVC pipe for maximum strength and protection.

THEORY OF OPERATION

The RF Isolator can reduce the amount of RF radiating from coax feeding an antenna. Stray RF can result in a loss of radiated power from the antenna, which will lead to a reduction in signal strength. This loss of power is critical when using a short or otherwise inefficient antenna, and/or using very low power.
