This is a desktop controller box for a Hy-Gain "Tailtwister" Antenna Rotator. It does not include the remote motor unit that actually rotates a directional antenna - it is this control box ONLY.
It will work with all of the "HAM-M" series rotators made by Telix, Hy-Gain, CDE and MFJ: Rotator series HAM-M, HAM-II, HAM-III, HAM-IV, T2X and the CD-44/TR-44 series units. This came from a local Amateur Radio Operator's Estate. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -.- -.
