This is the remote control box only for the MFJ-1786 or MFJ-1788 magnetic loop antenna. The control box contains a back lit VSWR meter and microcontroller circuitry that supplies DC voltage for motor control through the antenna coaxial cable through an internal bias tee.
The box requires a 9-15 VDC, ungrounded power source. The current draw is 6 mA on standby increasing to 20 mA while tuning, and 35 mA more if the meter lamp is turned on. The power jack on the back of this box accepts a 2.1mm coaxial plug with the center conductor positive. There is also an internal battery connection that can be used with 2 battery holders with 4 "AA" batteries in each for portable operation.
