Smartlock Pro - For SG-235

The SGC Smartlock is ideal for mobile use, or any installation where antenna conditions may change. It provides two external controls for the SG-230/237/239 Smartuner. The locking function prevents retuning despite changing antenna loads. The reset function forces the coupler into a retune cycle the next time a signal is transmitted. Tune and lock status is indicated by one green and one red blinking LED. Supplied with 9 foot connecting cable.
