So what is the voltage out the finals on a solid state transmitter?

Do you mean the DC voltage on the collectors of the output transistors
or the RF voltage into the feed line?

Ok, Don't call the modules "finals" then but what is the output voltage
to the antenna? I would like to know what the RF current is as the
output is supposed to be 50KW.

I'm surprised a smart person like you isn't familiar with Ohm's law...

To find the RF voltage for a 50 kW transmitter, assuming a 50 ohm
transmission line:

Simple Ohm's Law:

V= the square root of (RxW) (V=volts, W=watts, R=feed line impedance in
ohms...assume 50 ohms)

To find the current:

I= the square root of (W/R)

Sometimes you're just to, too, two clueless. :-)

You are such a retard. I was wondering what the line loss would be


Try again. You were NOT asking about the "line loss".

and I
am not familiar with the FCC rules.


Well, then could we say YOU are clueless?

The 50Kw could be the max the
transmitter puts out or the input to the antenna or it could be based on
antenna field strength measurements.


Again, could we say YOU are clueless?

And also the 50 ohms impedance would be another assumption on my part
but since a clueless wonder such as yourself generally proceeds on
unfounded assumptions you will not understand this.


You admit *YOU* know *NOTHING* about the power or impedance and yet you
accuse others of being "clueless".

Can you see the irony here? Or are you to, too, two clueless to get it?
