32 pill mobile amp. Swings 7000 watts. $2000 firm.

Be LOUD and PROUD!





How much drive does it require?

And, HOW BIG of a 440 Volt 3 Phase Sub-Station is required?
The corona off the gutters ought to remove the need for a yard
light, tho !

A typical efficiency is about 50%, possibly less at these current levels, so
figure14000W input, or 1000A at 14V? I'm going to bet that there's some
significant I^2R loss in that system.

Of course on the new car systems with the higher voltages, things will get a
lot easier.

I'm pretty sure that's a mobile amp Doug is selling. Must take quite
a bank of alternators.

More like a WELDER, GENERATOR or, one hell of an extension cord!
and, the antenna would need to be about 5 inches in diameter
to keep from melting!

7kW at 50 ohms isn't THAT much current.

What's the feedline connector?

BNC should work nicely.

I forget the math?
P=IxE and E=IxR so P=IxIxR? 7KW=IxIx50 7000/50=IxI 140=IxI
140=me twice
Damn now I've got a headache!
