How much drive does it require? It will easily fit in your ass if you get mopedope to give it a push. |

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. -- KC6ETE Dave's Engineering Page, www.dvanhorn.org Microcontroller Consultant, specializing in Atmel AVR -- |

Must take quite a bank of alternators. |

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? -- KC6ETE Dave's Engineering Page, www.dvanhorn.org Microcontroller Consultant, specializing in Atmel AVR |

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! Dave VanHorn wrote: 7kW at 50 ohms isn't THAT much current. What's the feedline connector? |
