Could an eighteen wheeler carry such a power source?

“Could an eighteen wheeler carry such a power source?”

Probably, but in my experiences, jamming units were positioned on the front line, and an unwieldy 18-wheeler would make one hell of a cumbersome target.

Could an eighteen wheeler carry such a power source?

The short answer is "yes", but it would have to be a separate electrical generator other than the truck's own system. The jammer pods require so much electrical power for the amplifiers that most of them are equipped with a high speed wind driven generator in the nose. The plane's internal electrical generators can't supply enough current to run the jammer pods, so they have to generate their own via wind turbines. A truck would have to carry a gas or diesel generator set in back to run a high powered jammer.
