Protect Your Remote Auto-Tuner with the Array Solutions Auto-Tuner Disconnect

You’ve spent a lot of money on that remote auto-tuner.  When bad weather threatens, nothing protects your auto-tuner better than a hard ground right at the auto-tuner output.  But how do you do this unless you go outside and disconnect and ground the auto-tuner output when it is not in use?  The answer is the Array Solutions Vertical Antenna & Auto-Tuner Disconnect, which automatically grounds the antenna feedpoint and auto-tuner output when the DC control voltage to the unit is disconnected.  The DC control voltage may be supplied via the Array Solutions BIAS-T MASTER, or through a separate DC connection.  The DPDT relay used in the ATD-1 has 3.1 kV of gap and arc capability, which means that the ATD-1 can be used with full legal limit feeding antennas with an SWR of 60:1.  So there is no need to worry about ATD-1 arc-over into the worst loads presented to your remote auto-tuner.   The Array Solutions ATD-1 is perfect for protecting your CG, SCG, ICOM, and other remote auto-tuners.
