That was a manual tuning analog receiver to be paired up with a LNA. Likely had a hand crank on the dish to move east/west or if it was super deluxe installation, a sidecar controller for moving the actuator!
As in the manual of their; "Automation" is certain today via satellite tv and the oldest receiver's were lna dependent; and downconverted was a heavy rg11 at 3.7-4.2 patched to the tuned and supplied; 18vdc: +14-18 vdc tuning voltages moved through the tp's and is still where the frequencies are located as the analog realm. The wires were amplica's also; and satellite was born on the forey as the names were many. 70 MHZ tiller will work the waveguide; > by 1980 they moved the tuner using a blockcoverted band to a 50 MHZ huh wiring became very easy? it did have a sidecar box that was never manufdactured; and bought by houston tracker.The first az/el; axis was the human crankery powered ; with skew available for each. My personal viewpoint was the amplica; and even had a module from GI black open to it CAN BE FIXED no more signals STILL IN electric shop's and BEAR moving DISH MUST BE 11...
