Vermin are de-tagging people who do not have sub, from main street box.
The attenuators do reduce the signal, but i have read the signal strength is not the issue as it in the 80's%, but its the fluctuations in the signal causing picture break up. So i think the attenuators must dampen these fluctuations. Its worked for me, but as i said earlier i have to adjust it for every channel.
Just hope i can get it back to normal.
