I cured my remaining minor 40m interference to my DirecTV system (only band I have a problem on) by attaching a 1/4 wave 40m radial on the back of the dish.

My RF sniffer didn't show any high RF from the 40/80/160 radials running near the dish, but there was a peak in the RF along the sheet metal flashing within about 3 feet of the dish.

Anyone (as old as me) remember when all you had to do to cure TVI was run a 6" wide ground buss on the desk behind your rig with a LP filter bolted to it, run a 4' wire to a ground rod out side the shack and put a HP filter on the TV ? hi hi

Hey...... whatever works!!

Remember, E = M * C^2 was not the entire equation.
