Sometimes the combiner you are using has problems. What happens to WMYD when you connect the UHF antenna to the tuner with and without the preamp, bypassing the combiner?

UHF Ant > FM filter > grounding block > tuner

UHF Ant > FM filter > preamp > grounding block > power inserter > tuner

Which FM filter are you using?
