Impatient you are.
Not an industry person, but maybe I can help.
Do you own either of those antennas already? Are you planning to mount your antennas on the roof, clear of any surrounding obstructions?
I ask because I wonder why you focus on the DB4e instead of the DB8e if you are buying new.
The Clearstream 5 will miss VHF low channels 2-6.
I would probably buy an Antennas Direct DB8e and an Antennacraft HD1850 and connect them to the UHF and VHF ports of an RCA TVPRAMP1R. This would give you a single lead-in that combines VHF and UHF. Then I'd aim them both south-ish (168) and see what I got.
To me, it looks like a difficult environment to get all the major networks. The closest NBC affiliate I see here is WNBC from NYC, ch 28 way down the list - but no co-channel interference. I'd probably start with the DB8e and put it as high as I could, pointed toward the big group of stations at 168 magnetic.
