MFJ-926B 200 WATT REMOTE AUTOMATIC ANTENNA TUNER (SECOND)

This is called a second because you would be the second owner. These are used automatic antenna tuners that have been refurbished and returned to the original specifications.  This is a remote 200 Watt automatic antenna tuner that includes the BiasTee Power Injector.  Seconds could have cosmetic defects, thus the lower pricing.
