I have >100ft run of cable from my 622 to TV2. Of course, I know that I can't get HD on TV2, but I'm having problems getting full-quality SD. I also had a problem with just TV antenna losses in the system and years ago installed an amplified distribution system. I quickly found out that it doesn't work for the 622 modulator. In fact, I had to disconnect the amplifier and join cables with a barrel connector to get TV2 to accept the signal at all. Then, I did notice some degradation from the picture quality that I had from a temporary direct hookup of about 40 ft of cable going up the stairwell. The longer cable run is of course because of going through walls, ceilings, etc. to keep the cable hidden. I installed the distribution system myself in an existing structure and didn't have the luxury of choosing the shortest possible route. I plan to split the signal further for a couple of other "TV2"s. Are there signal amplifiers for the modulator signal used by the 622? What are my other options? I don't have a reasonable way to shorten the distance.
