st-1.png

ST-1   Stepper Motor Kit To Remotely Control The Palstar BT1500A Balanced Antenna Tuning Unit (See In "Documentation" At Top Of Home Page).  

This Kit Requires No Holes Drilled To Install On The BT1500A!  The BT1500A Can Be Completely Restored To Factory Original After The ST-1 Has Been Removed. 

The ST-1 Implemented With The StepperTune Controller (see at steppertune.com) Allows  Remote Control Of The BT1500A.   Control Cable Comprised Of One CAT5 Cable!

This Allows One To Use Coaxial Cable From The Transmitter Out To The ATU Near The Ladder Line And Antenna.  By Remotely Locating The ATU, A 1:1 SWR Match On The Coax May Be Acquired Which Makes The Antenna System Extremely Efficient And With A Balanced ATU, Good Ladder Line Symmetry Is Maintained Which Minimizes Feed Line Radiation And Extraneous Noise Pickup.
