Product Description

  • 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.

  • The MFJ 1:1 Current 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 Current Balun 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.

    I have not used this balun at this time, it looks to be well constructed and one about the Ham Shop ships at the speed of light, I plan on doing more business with them in the future

  2. Nice and easy current balun for antenna 5 Star Review

    Posted by on 14th Jun 2016

    I used this with a 80 meter resonant dipole and it had a very low SWR. It was easy to hook up and I soldered the leads to the antenna wire to ensure a good connection. The supplied hardware was tight and good quality.

    Operation is as expected. MFJ could have added a screw lug for the pigtail connection instead of a hole in the body. It would have made changing the pig tail wire easier in the future.
