I have had similar positive results with common-mode chokes.
It should be noted that the actual antenna should be kept away from these local noise sources for the benefit to be realized.
Although the choke will prevent common-mode noise induced on the transmission line from entering the receiver, noise signals induced on the actual antenna will not be attenuated by the choke.
Users of indoor or attic antennas will not see as much benefit from the use of common-mode chokes.
