Dave,

"should" being the operative word.

It isn't always the case that feedline radiation is insignificant. Keep in
mind that the transmitter feedline might also be much closer to the
affected device, its power line and its feedline.

It is also fair to say that there is a whole family of ham myths that
revolve around feedlines being the cause of RFI, TVI, generation of
harmonics, causual links between open wire feedline and interference, etc.
