This goes to show you it is usually not OUR problem.
My old DirecTV receiver needed tons of ferrite to get the RF out of it.
Tech installed a new DVR receiver with dual coax, bare bones, no ferrite.
Full power with amp and beam pointed at dish there is only a slight jiggle of
the picture on 20 and a tiny bit of audio gets into the TV speakers on 10
160-30 with the vertical is completely clean on the DVR and were a nighmare to
clean up on the old receiver.
Remember, E = M * C^2 was not the entire equation.
