I tried 260 first, then 115 (current direction and the setup used to pickup # of channels listed in my previous post).

3412 is right off of the antenna (maybe 6 feet of cable away at most).

                          / 
4221 > coax 6 ft > 3412 >  
                          \ 
                           coax 60 ft > 1st floor TV

Very similar, I'd say it's closer to this:

                           coax 50 ft > cable extension adapter male-to-male (in junction box) > coax 20 ft (guess) > 2nd floor coax wall jack > coax 6 ft> 2nd floor TV
                          / 
4221 > coax 6 ft > 3412 >  
                          \ 
                           coax 50 ft > cable extension adapter male-to-male (in junction box) > coax 60 ft (guess) > 1st floor coax wall jack> coax 25 ft (through wall) > 1st floor TV

Note: Up to this point, I have not had both 3412 outputs hooked up to both paths. I have been switching between paths where the coax 50 ft enters the junction box. After I verify that I can get all the channels I want on the downstairs TV, I plan to run the extra 50 ft coax and truly split the signal to both paths.

Also, is it possible that the 25 feet of coax cable that I run through the wall on the 1st floor to the TV would degrade the signal if it weren't 75 ohm quad shielded? I read somewhere that this was important. I bought this years ago, and I'm not sure if it is 75 ohm quad shielded or not.

I will pull the list when I get home for both TVs.

I tried looking for this option on my 1st floor TV, but couldn't find anything after experimenting or googling the TV. My TVs are listed below. Maybe someone can help me locate a way to check it.

• Vizio M552I-B2 (1st floor TV)
• LG 42LD550 (2nd floor TV)
