[Hallicrafters] RTMA Dummy Antenna needed for alignment?

[Edward B Richards]

OK, Jim;

I understand. You would put the 50 ohm resistor at the generator's
output, before the coax to the receiver. Actually, most hi end generators
have a 50 ohm output. I know my UG25F does. I agree that too much energy
is wasted on impedance matching. Actually, the best way is to connect the
receiver in it's final configuration and peak the antenna coils to a
station or just peak the noise. No big deal. Good luck.
