Description
100 ohms unbalanced to 50 Ohms unbalanced
Unlike Baluns, Unun's (unbalanced to unbalanced) provide impedance transformation for antennas that are naturally unbalanced because of their design configuration. Even though the unun's appear small is size, they are able to handle very high power (2kW continuous - matched condition) because of their excellent efficiency. It should be noted that the manner in which ununs must be wound provides NO common mode or RF choking impedance. This unit can be built to either 100 or 112 ohms so please be sure to select the value required when ordering.
Other unun ratios are available by contacting us via the methods shown in the About Us section.
