> What's the intent and application of this?

I'm working with a 1930s MOPA transmitter, 
which is speced to deliver about 3 watts out.
100 pFd in series with 5 Ohms is the "phantom antenna"
designed for it.   Scope says 100 Volts PtP or about 
70 Volts RMS across the load at 3870 KC.
Z of the load should be about 411 Ohms.
I know the output is low and I'm not finished looking
for the cause, but I don't believe the solutions I'm 
getting, so I'd like to see how the many people 
smarter than me solve this problem, so I can 
find my errors.

Thanks,
Dave S.
