RF Isolator Balun MFJ-915 Choke For Ham & CB Radio HF Antennas MFJ Feature :
  • * Eliminate Stray RF from Amateur & CB Radio Antenna Feedlines.
  • * Helps Reduce Interference & TVI.
  • * For 1.8-30Mhz HF uses.
  • * 1:1 , 50 Ohms; Accepts Coax cables with PL-259 Connectors.


  • 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.
