Try re-aiming the antenna with no amplifiers connected, using just one TV.
With noise margins predicted to be 30 dB or higher, I expect that you should have enough signal power to drive 100' of coax and a 4-way split, all with no amplifier.
You already own the 4-port PCT amp which has a fairly high input capacity, so you can go ahead and use it rather than buying a passive splitter. However, the second amp must be overloading, and even if it isn't, it's adding noise that works against you.
Follow up with Antennas Direct. Their VHF retrofit kit was not on their web site when I checked earlier (edit: per ADTech, they are on the website), but they have been testing them in the field for some time now.
(FWIW: The total loss of 100' of RG-6 is less than 7 dB at the top end of the UHF band. A 4-way splitter should not have more than 7 or 8 dB of insertion loss. The math says you should have less than 15 dB total loss between the antenna and the most distant TV. The CS2 has forward gain that offsets as much as half of that cable+splitter loss, which would leave a NM of over 20dB at the TV tuner.)

Reason: ADTech says the retrofit kit is available through their webiste
