Hello, I have just installed an Omni directional antenna I was given as a gift hopping to get rid of Comcast. The antenna is mounted in the attic and is (that the moment) connected to only one TV. The roof is asphalt shingle.
The antenna is about 25’ off the ground and I receive a fair amount of Channels, my problem is that channels 5.1 and 7.1 both pixelate badly. Attach is the TV fool channel map for my area of Nashua, NH.

Based on the TV Fool map for my location both channels transmitters are within 2° of each other and their signal power is -65.9 dBm and -71.6 dBm
I have tried a cellular (3G/4G) filter, a pre-amp and an amplifier with 8 Db gain.
Nothing has made much difference. Any thoughts
Thanks.
