Several years ago I had a problem on 2 Meters with cable RFI... I
looked at the cable junction in the back of our yard... There was a
cable running out of it, across the ground, and into the back yard of
someone about 400 feet away... Called the cable company, the problem
disappeared, and so thd the illegal splice... It takes a log of
"hutzpah" to do something like that... I can't imagine running a big
black arrow to my house like that... Oh well... RFI is gone...
