Welcome to the forum, kokadjo:

My research led me to purchase and install a Weingard HD7698P Platinum HD Series Antenna. It is installed on the highest peak of my roof which puts it approximately 40ft above ground level.
That sounds like the right thing to do. I see a lot of trees in your area; I hope there aren't any in the signal path. See attachment 1.

Currently I have no preamplifier and it connects directly to my upstairs tv as I gauge reception before running lines/splitters/etc.
Now that you have tried it without, it's time to try it with a preamp. I don't see any very strong local FM signals to cause interference, but you should try an FM filter. Some preamps have one built in. See attachment 2.

My antenna is pointed at 265 degrees (based on my iphone compass app).
They are known to have poor accuracy; use a real compass for 265 degrees magnetic.

My two main questions are why would I be able to receive other UHF stations from the same broadcast site with similar power, but not NBC and CBS.
My guess would be the difficult terrain between ESB and your location. If you look at the coverage map, you will see you are in a signal dead zone, attachment 3.
Quote:
My other question is, should I have purchased an antenna that receives VHF-Low as they seem to broadcast on that frequency as well.
No, the antenna needed is determined by the real channel number, not the virtual channel number.
VHF-Low, real channels 2-6
VHF-High, real channels 7-13
UHF, real channels 14-51

Other potentially pertinent information is that I just do a simple channel scan on my Sharp TV to find stations. I cannot figure out how to manually search for a station.
Every TV is different; I'm not familiar with that brand. My Sony allows me to add a channel after scan.
Some Samsungs can accept an added channel by entering the virtual channel number 2.1 or the real RF channel number 33; try it.
Quote:
Also, my area is quite hilly and wooded.
Yeah, I expected that; both are serious barriers.
Quote:
My tv analysis says that channel 33 is prone to co-channel interference.
You are correct; it's from WFSB-DT, which is 18.8 dB weaker and in another direction. I don't see it as a serious threat.

does anyone know of a way to also receive a NY CBS feed?
Have a friend in NYC stream it to you over the internet with a slingbox.
