I don't think that the antenna is likely to be much connected with noise
coming out of control circuitry.  The input connection _does_ (in every
instance that I've looked at) go into a shielded metal enclosure...

If something in the set was messing with this I suspect that perhaps it
would be doing it a little bit later on in the signal chain?
