Commentary:
The MRA5 was introduced in 1973. The antenna on it could be separated and placed up to 25 metres from the control unit. As a result, it could be placed on a mast high above the control unit to give a line of sight over ground obstacles. The image on the right above copied from the operator’s manual shows the antenna separated from the control unit and a car battery to provide power to the unit.
