WMAZ (digital channel 4) - ~70% (picture has noticeable break ups)
WGXA (digital channel 32) - ~40-50% (no lock or picture)
WMGT (digital channel 40) - ~50-60% (no lock or picture)
Will taking the antenna up another 5 feet increase my signal any?
It worth a try if it is not that much trouble. But you should also try lowering it a few feet as well. Did you try to tweak the aim and checking for better signal strength? A single connector should have minimal impact. Have you tried it without the CM 7777 in the path?
I plugged your zip code into antennaweb and could not get WMAZ-DT to show up even adding an antenna height of 1000' for the zip. Hilly area? WGXA-DT is on DT 16, not 32. But there is a WPGA-DT ABC 32 on UHF 32. Several of these stations are not at very high power. The FCC database also has low power STA entries for the station, but they may be at the higher permit power.
WMAZ-DT CBS 13, DT = ch 4, 7 kW, 181 meters HAAT (not that high power even for low VHF)
WGXA-DT Fox 24, DT = ch 16, STA power = 1.16 kW, full power = 1000 kW, 226 m HAAT (probably operating at full power, you be lucky to see anything at 1.16 kW)
WMGT-DT NBC 41, DT = 40, STA power = 3.3 kW, full = 110 kW, 189 m HAAT (110 kW is not a strong power level for UHF)
WPGA-DT ABC 32, DT = 32, power = 18 or 100 kW, 186 m HAAT.
Of these four stations, only WGXA-DT Fox 24 is at high power. Assuming you meant to say WPGA-DT ABC digital channel 32, all three have lower broadcast power levels and are only 181 to 189 meters Height Above Average Terrain (HAAT). You may need to get a dedicated UHF antenna for WMGT-DT and WPGA-DT.
