Absolutely not. Actually the rule of thumb, for lack of a better term at the
moment, is just the opposite. RF signals usually travel further at lower
frequencies. However this is also affected by the resonance of the antenna
being used and the distance between the source and the antenna. If an
antenna is equally resonant on 80 meters and 10 meters and the source were
10 meters away from the antenna the RF wave length would reach the antenna
at the resonant peak and would be stronger than a noise that reached the
same antenna at the null of the 80 meter wave length while monitoring the 80
meter band.

Sorry I'm on a break from applying these principles and can't elaborate
Ask your RFI investigator to call me and I'll be happy to assist him and
