Thanks for the reply


What about connecting to the same ground rod the house panel connects
to? *Or would that introduce AC hum?


Just curious. *On a modern radio, (without a coax connector), if I was
to connect a 50ft. (or more) outdoor wire to the rabbit ear using an
alligator clip, would that give better reception?


No You will cause the front end to go non-linear and produce unwanted IMD


This can be successful if the lead in wire remains insulated, and you
wrap the *insulated* wire around the whip a few times for an inductive
connection. You can adjust the sensitivity quite nicely this way
depending on how may coil wraps you use.
