Product Description
-
The MFJ-918 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-918 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

Nice and easy current balun for antenna
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.

MFJ - 918 Balun
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.
