I am finally getting real serious about getting organized and I today rediscovered this unknown to me connector and cable.
I may have posted this long ago; if so, I apologize, as I cannot find any record.

Connector pattern, looking at face of this connector, female:

…………….A………

………B………..F…..

………C……..…E …..

…………….D……….

ITT CANNON   MS3106E14S-6S(6)

Exiting the connector are black and red wires, about 14 gauge, about 10 ft. long terminating each in an alligator clip, like a clip size used on common SLA battery.

Also a RG-58/U about 15 ft long terminating in a PL-259.

So, what was this made for?
