It's why many antennas use a DC shunt - makes a good RFI trap for noises entering into the antenna from broad banded sources - including their new 5G tower "cap" setups that provide local short range coverage in neighborhoods.


IF you got time, might want to take a short drive around the neighborhood with your cars' AM radio tuned to a distant station (or CB) - so the noise emanating from the source can be located by listening for the "blanking" or washing out of the weaker distant signal overcome by the emissions of this new device

Yes, coax pick noise too.
I would use choke balun at antenna feed point and another where coax enter you house/garage etc.
Also I advise to insulate antenna from a mast (if conductive).

I did call the power company and told them I thought I was getting noise from the power lines. They said they would notify our local repair crew and have them check it out. We will see what happens.
I will have to check out a balun.... and yes the the mast is conductive and the coax is zip tied to it. I may not get that done till spring as the weather is getting to cold to be working outside for an old guy like me.
Thank you so much Mike
