32 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. This unit is excellent for matching antennas such as inverted L's and other unbalanced antennas with low feedpoint impedance.
Other unun ratios are available by contacting us via the methods shown in the About Us section.
