This month's discussion is about BalUns. These passive devices do a whole host of things for the improvement of your antenna system. Two types are covered, the Voltage BalUn and the Current BalUn. The two work pretty much the same at the feed point.
Core saturation may be a problem with a Voltage BalUn. Care should be taken not to over-drive the device.
Transmission line radiation can be inhibited/controlled with the Current BalUn.
