I have been diligently working to get reception of channel 6 and channel 12 in the western phila burbs (think Downingtown exit off pa turnpike). I started with a UHF/VHF mounted in the attic. Great reception for about 33 channels, but no 6 or 12. After trying home made di-pole, decided to add a
Winegard Company Compact Video Antenna (HD7000R) for Lo VHF reception. Matched the coax lengths to eliminate out of phase interference. Tried a VHF/UHF combiner with no luck (actually blocked low VHF) , but found the reversed splitter worked fine as a combiner. Added a [Winegard LNA-200 Boost XT HDTV Preamplifier - and now Rx’ 58 channels including the half dozen or so channel 2.X.
However - Channel 6.X (low VHF) and 12.X (VHF) come in at 100% signal strength, but only 40-45% signal quality. Pixilated picture that drifts signal quality to occasionally over 50%, but not enough tobe watchable. Tried throwing an FM trap in line to see if the low band VHF quality was being overpowered by local FM signals - no dice. Just reduced the number of channels available.
I have used a compass to direct both antennas to 109 degrees - still no help. All signals that I want are coming out of phila btw.
At my wits end here. I really do not want to mount the VHF on the roof of a townhouse - just butt ugly.
Any ideas on how to improve signal quality when i already have 100% strength? these 2 channels seem to be very weather/terrain dependent.
