Universal Magnetic Balun UMB 130

Universal Magnetic Balun UMB 130

The UMB130 is a receiving antenna Balun  with a 9:1 impedance ratio.

The feeder winding is isolated from the antenna to reduce mains borne noise and antenna/feeder interaction. The UMB allows for Longwire, dipole and Terminated Loop to use a coaxial feeder cable without an antenna tuner. The UMB is specifically designed to reduce Mains Borne Noise such as TVs, by ensuring that the antenna earth return path is isolated from the receiver/mains earth.
