The ATS is a 1KW Antenna Tuning System.  It consists of 3 main parts: 

  1. ATS-MCU, the Master Control Unit, which contains the famous cross-needle SWR meter
  2. ATS-CU, a directional coupler that samples forward and reverse power
  3. ATS-TU, the remote, fiberglass waterproof tuning unit that is intended to attach directly to a 35' whip antenna.

There was, in addition, an optional AC-218 loading coil.

Controls on the MCU allowed various functions inside the remote TU to be adjusted remotely.

I don't have an ATS-2 front view.. it'll show up eventually! 5810.8-7.  ATS-2 MCU top view.  I believe, best I can tell, that this is an early production verwion of the MCU-2. 661.10-3.  ATS-2 MCU top view.  This is the later production version of the MCU-2. 5911.6-25 MCU-2 bottom view.
