[Hallicrafters] RTMA Dummy Antenna needed for alignment?

[Edward B Richards]

Jim;

You don't say where to put the resistor. If the generator has a 50 ohm
output impedance you don't want to put it across the receivers antenna
terminals as you would be double terminating the sig gen. The radio
already is a termination. If you are going to be using 50 ohm coax feed
line, just peak the antenna coils into the generator. That will optimize
the radio for a 50 ohm input.
