Odd occurrence this morning is all channels were coming in great EXCEPT WCCU from which we had no reception at all. Very strange. Lots of bad weather today, so that could be a factor.
Trees block TV signals, especially when they are wet.

Scroll down to Trees and UHF if the hdtvprimer.com site is up.

extract from that page:



Because the WCCU antenna is in the attic, you could try the suggestion by ADTech to add the Antennas Direct Juice preamp. That preamp resists overload as he said, but it might overload the TV tuner, in which case you could insert an inexpensive attenuator to prevent that.

You also have a very strong local FM transmitter, WGNJ, also to the north, that might cause overload:

Since the attic antenna also covers VHF, it will make the WGNJ FM signal even stronger. You could try inserting an FM filter in the coax between the antenna and the preamp input, but for some strange reason Antennas Direct has discontinued their FM filter and they were the only regular source left:

As a substitute, you can insert a UVSJ, UHF and common ports, which will pass only UHF signals and block VHF and FM.

WCCU attic antenna > UVSJ > Juice preamp > coax > power inserter > TV

This is an experiment; I can not offer a guarantee.
