Very likely it is riding as a common mode signal on the coax leaving his 
TV. Maybe on the power cable for his TV also. And perhaps radiated 
directly from the TV because it is badly shielded.

Study the tutorial, then buy toroids and wind the coax around them to 
form multi-turn chokes, using the winding guidelines in the tutorial. 
They can fix everything but the shielding part of the problem. For that 
you need the bucket treatment.
