[RFI] can a tower re-radiate RFI?

[WW3S]

And can it be prevented? Trying to track down a loud “buzz” on 160/80.......I used to be able to kill it by turning off the breaker to my outdoor pole light with a photo-eye on it......now, that doesnt even phase it.....found several sources in the house last night (cfl bulbs, a bad flourescent tube, external hard drive power supply) but none even touched the noise I was hearing.....so today, had a little time when I got home from work before dark to walk around the yard with a portable SW radio.....thought maybe it was pad moount power transformer in the neighbors yard, nope...tried the power ped in the corner of my yard, nope...maybe my relatively new “smart” power meter, nope.......then as I walked past the tower, I picked up the buzz in the portable......really bad the closer I got to the tower......thought maybe it was one of the cables, nope.....it seems to be coming from the tower, 50ft Rohn 25....is that possible? Is the tower picking up RFI from a remote source and re-radiating it? It certainly couldnt be generating RFI could it?
