Ok here it is. Zip code 02050 R/S 1260 ant uhf only,25 ft rg6-qs.Samsung ts-450 set-top. All my locals abc,nbc,cbs,pbs,pax,wb,ect. come in at 60-75%. except fox 40% which I really wanted. So I installed a phillips preamp and raised the ant 2ft higher, now 5ft above roof line and all are at 90-100%,except fox, now has digital break-up every 2-3 minutes. Or sometimes the audio and video won't match. Multipath?Too much signal? fox is showing 100%, So I tried a splitter and nothing happened. I've tried moving the ant on the mast 20* side to side and nothing. Should I try moving the whole ant to another location. I'm very fustrated and want fox 100%, football.
