It seems like everyone thinks they can build baluns ... and they make all sorts of incredible claims to prove it. We don't make claims, we print specifications. Most commercially produced baluns are Voltage- type baluns. The Current-type balunâ¢ is superior to simple 'Voltage-type' baluns in several ways.
