While we're talking about transmitters, let me ask this question: Lets
say I have a video opamp that will put out +-10V at 1 MHz into 377
ohms... can I hook this to an antenna? P=E^2/R=100/377= 260mw In
other words, the 'traditional' approach of making everything 50 ohms
and using tuned class c amps is just how it was done with tubes in the
40s right? If the impedance of the antenna is 377 ohms, and I can drive
it direct, thats all it takes, right?
