Our baluns have a bolted, clear polycarbonate case and are not filled with insulating plastic like other baluns. This makes the production of these baluns much more expensive, also because we still have to make the baluns weather resistant, but this method has a clear benefit: In case of an 'accident' you can fix the balun yourself. And it is much lighter than other, conventional baluns. Each balun has a hook formounting and is equipped with a PL socket.
