You didn't say what ferrite core material you're using or how many turns.
It takes more turns for 160 than for 80 and above, and #31 material
works much better than #43 or #61. I'd try to get at least 14 turns,
and more is better. If you've already done that much, with #31 material,
add a second choke in series.
The best place for the choke(s) is as close as practical to the U-Verse
box that is receiving the signal. A choke is unlikely to do much good
in/near a telephone splice box. It's the electronics that detects the
RF, and that's where the choke should be.
