Looking for some assistance in OTA Reception and Antenna choice. I'm south of Charlotte in the Waxhaw (28173) area and have two blocks of transmitters I'm trying to pick up, one batch about 20 miles away due north (0-6 degrees) and another batch about 40 miles to the northwest (320 degrees). Here's the TVFool Signal Report from my location.
So here's my current setup, and I'll try to be as detailed as possible, so sorry for the long post
I've currently got two antennas mounted in my attic, which is about 25-30' above ground level. The both do have to punch through an exterior wall of plywood and vinyl siding, and then across the street there are some 40-50' tall trees, but there's nothing else blocking LoS. The first antenna is an Antennas Direct Clearstream 4
that is pointing at the 20 mile transmitters at approximately 0 degrees. The second antenna is an Antennas Direct DB4e
that is pointed at the 40 mile transmitters at about 320 degrees.
Out of each I have 4' Coax feeding into a ChannelPlus 5-1000 MHz Combiner.
Then from the Combiner a single 4' coax feeds into an Antennas Direct CPA-19 Pre-Amplifier
. Then from the Pre-amp I've got about a 50' foot coax run that runs out of the house and down to RF IN port on a Viewsonics VSMA-608C
whole house Amplifier/Splitter installed by Time Warner back in the day. From here, there's 6 home runs going out various rooms in the house. I've got all those home runs terminated except for one that is feeding a Tivo Roamio OTA on the lower level. (I have tried to take the VSMA-608C out of the mix by directly connecting the 50' antenna coax to the Tivo Home Run, but didn't get any better results.)
All that being said, while I'm able to pick up just about everything to the North and Northwest, the strongest signal I'm able to get on any channel is a signal strength of 72 out of 100 on any of the channels on the Tivo. Some channels (Fox in particular) aren't coming in very well at all. I'm primarily concerned with UHF channels, so, my question is, am I pretty much doing the best I can? Is there a better antenna/amplifier setup that I might be able to try? I've seen a few that seem to have 5-15 more dB gain than the two I already have. Any thoughts or suggestions would be appreciated!
