Signal levels at your location are far in excess of the input capacity of many amplifiers. An amplifier is one of the very last options I would suggest in this case.
A few possibilities:
(1) Your home made antenna is badly de-tuned at channel 48 (WOPX's real broadcast channel). -- What happens when you remove all splitters and connect the antenna to the 2250 only?
(2) The antenna is OK and you are receiving enough signal (TV + FM) to overload the Hauppauge 2250 front end. -- Have you tried installing a passive FM trap?
(3) There is a bad splitter, cable, connector, etc. -- Have you done a thorough inspection? Including the parts that "can't be bad"?
(4) You have the antenna located in a cold spot for a couple of signals. -- Have you tried adjusting aim and the location of the antenna? Is it inside or out?
Mounted outside, in the clear, a factory built DB-4 would be PLENTY of antenna for all of the UHF signals south east of you.. An RCA ANT-751 would be quite sufficient and it would cover the high VHF signals also. Either antenna should recover enough signal to drive a 4-way split with no amplifier.
