You need a better class of neighbor. If it were me, and the antenna was on MY property, the neighbor would be in jail for malicious destruction of property!!!
You need to use common noise tracking techniques and find out what the problem is. It could be power line problems, a battery charger for power tools an aquarium heater, a door bell transformer. First thing is to run your radio on a battery and turn off your breakers one by one to eliminate the possibility that the problem is in your trailer. If it's not, then go around the neighborhood with a portable AM radio and listen for the noise. You might give your power company a call and ask them to check the power lines, pole pigs and disconnects in your area.
As for the Butternut, it's a great antenna but not really good for state MARS nets, the takeoff angle is too low for the 100-200 mile radius you need for MARS. If you must use it, you need 20-30 radials about 25' long, as a minimum.
