My suggestion would be our DB8e plus our PA18 preamplifier. RG6, either low loss or quad shield is fine, as well as an appropriate mount and/or mast, depending on where you choose to install the antenna. No rotor is needed if you want to focus individually on St Louis or the Illinois PBS station. You *might* find that the DB8e can be used in its split-aiming configuration and get both.

If you want to add an attempt for the two VHF stations out of Quincy, add a ClearStream 5. You'll either need a long enough mast for both or a separate mast/mount for the second antenna if you add this second antenna. I'd probably explore the UHF reception from St. Louis first as it's probably your best bet, particularly during the seasons when the trees are bare.

Do keep this question in mind... "If that spot shouldn't be available, how about an alternate ground-mounted location that clears that tree?"

It really is that important that the antenna not be behind trees when dealing with very weak UHF signals. I cannot stress this enough if reliable reception is desired - which is why I keep harping on the subject.
