A simple DB2 or DB4 or small UHF Yagi should work fine. As BCF68 pointed out, you don't need any VHF capability for the St Louis stations as we're UHF-only. You have plenty of signal power available, so a balanced 3-way splitter should do fine for sharing the signal.
The only VHF station within receiving range is WSIU (PBS from SIU-Carbondale) which has its main channel 8 transmitter near DuQuoin. If you want that signal. you'd need to install a separate high-VHF antenna and combine it to the other antenna via a UVSJ. Please note that WSIU has applied for and has been issued construction permits for UHF translators, one of which will cover your area when built. At last word, they didn't have funding to build them. They'll probably need to run beg-a-thons to raise that cash.
