| The two capacitors used in the 291 are 1000 volt 50-250 pF variables connected in series with a 47 tap rotary inductor (0.5-24 uh) shunted to ground. This tuner can be used with a single 50 ohm coax input and output, or has a wing-nut lug for use with end-fed longwire antennas. Extra capacitance can be added externally to the back panel for increasing the matching range if desired. | The two capacitors used in the 291 are 1000 volt 50-250 pF variables connected in series with a 47 tap rotary inductor (0.5-24 uh) shunted to ground.
