- | Matches 50 ohm unbalanced output to variety of balanced or unbalanced antenna impedances. 46-tap inductor allows vernier adjustment. 200 watts intermittant, 100 watts continuous. | + | The Model 227 antenna tuner is an inductive/capacitive network used for matching unbalanced 50 - 75 ohm output impedances of transmitters and transceivers to a variety of loads, both balanced and unbalanced. It operates over a frequency range of 1.8 to 30 MHz. It has a built-in antenna select switch which permits bypassing the tuner or selection of three different antennas. Same as Model [[228]] but without the SWR bridge/meter. |
