Umm, your schematic looks a lot different than mine. Hold off on the changes until I've got it right.
First, I see that you have the 2 yagis connected to the input of the first LNA-200. How are you doing that? How can you insert two coax lines into one jack?
Second, why is there a splitter between the first LNA-200 and the UVSJ? A splitter is used to divide one coax line into two or combine two lines into one. A UVSJ is a UHF-VHF Separator-Joiner, used to combine a VHF antenna with a UHF antenna.
Third, where are the power inserters for the two LNA-200s?
