InnovAntennas 144MHz Current Baluns

InnovAntennas 144MHz Current Baluns help to keep common mode currents off your feedline and they ensure that you get the best performance out of your antennas. These InnovAntenna baluns feature a ferrite core covered in a glue filled UV stable heat-shrink. Ring terminals allow for easy connection to the feed point of your Yagi antenna.
Why use a balun? When an unbalanced coaxial feedline connects to a balanced antenna, unwanted currents can flow along the coax, distorting your antenna pattern and reducing its Front-to-Back ratio. These currents can also introduce RF interference in your home and even your neighbors' homes. Additionally, the coax can act as an antenna, picking up noise and degrading weak-signal reception. InnovAntennas 144MHz Current Baluns prevent these issues by properly matching your antenna's balanced feedpoint to your unbalanced coax system.
