RF Isolator Balun MFJ-915 Choke For Ham & CB Radio HF Antennas MFJ
The MFJ-915 RF Isolator is a 1:1 Current Balun, designed to be placed in line with any 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, TVI, interference 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. Great when used in conjunction with a TVI filter too.SO-239 Input & output connectors.
