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.Specifications
