Do I have it right now?

Code:
               C4 > LNA-200 > Pwr Inserter
                                          \  U
CH 7 yagi                                  UVSJ > dist amp > coax > 4 TVs
         \                                /  V   
         splitter > LNA-200 > Pwr Inserter 
         /
CH 8 yagi
If I have it right, disconnect the CH 8 yagi and connect the CH 7 yagi directly to the VHF LNA to see how CH7 does; it's your weakest signal.

What UVSJ are you using; what does it say on it?

What distribution amp are you using?

I don't see any advantage of using two LNA-200s. You could use just one to amplify UHF and VHF.

Code:
             C4 > 
                 \  U
CH 7 yagi         UVSJ > LNA-200 > Power Inserter > dist amp > coax > 4 TVs
         \       /  V   
         splitter  
         /
CH 8 yagi
If CH 7 comes in OK without the CH 8 yagi connected, then the Tin Lee AC7 might work.

Call them and talk to one of their engineers and email your tvfool report to him.

         AC7 CH.7 > LNA-200 > Pwr Inserter 
         /
CH 8 yagi
