Since the primary interference concern appears to be TV related, if it arises you can install a low pass filter between the radio and antenna. This type of interference would likely be harmonically related and these filter can provide upwards of 80 attenuation to these harmonics. They do nothing to prevent direct RFI to sound systems, landlines, ect. Most TV broadcast takes place in the High Band and UHF spectrum today. That digital signal is much more resistant to CB interference.
