The unun should find some important applications. Until recently, they have been literally impossible to obtain. But now they can be designed to match 50-ohm cable to loads as small as 3.125 ohms and as high as 800 ohms (both unbalanced loads). They can come in low-power and high-power versions as well as multimatch designs. An important application for ununs is to match 50 ohm cable to the input impedance of ground-fed antennas such as verticals, slopers, inverted L's and towers performing as verticals. Since ground losses play a large role with these systems, a knowledge of the input impedance of the antenna as well as the ground loss is important in determining the optimum impedance ratio. The low-power multimatch unun should find use in the operation room when an unfavorable impedance is presented to the transceiver. Also, a high impedance, multimatch unun can be dasily designed to match 50 ohm cable to the input impedance of beverage antennas. It should also be pointed out that ununs can be employed in series with baluns to provide a host of wideband baluns and ununs with ratios which have been previously unattainable.
