Nashville Tn ATSC 3.0
I have a condo on Lake Barkley that easily gets WPSD channel 6 (virtual) on ATSC 1.0. All other major networks are inaccessible.Nashville is now ATSC 3.0 on the major networks. If and when the NextGen tuners are available, would I have a reasonable shot at them given a wider area and a lesser noise margin?
My coordinates are 37.01118886849936 and -88.147988319697.
So far, Nashville coverage maps show a wide area but info on reception seems minimal or nonexistent. Any info is appreciated.

Hello, dbseeker; here is a rabbitears.info report for your Lake Barkley location:
https://www.rabbitears.info/searchma...tudy_id=166121
The NBC signal is fairly weak, but it is better than the rest of the major networks. There is a hill in the signal path just before your location:
You have a good chance of receiving NBC with a high-gain outdoor antenna in the clear.

What I was referring to was a possibly more extended Nashville coverage eventually with the Nextgen tuner. However this article appears to say coverage may vary depending on data rates and their effect on SNR and range. Nashville is now on the 3.0 market and was curious if their was info on their coverage map.
Thanks, Rabbit

Thank you for the link to the interesting article; I hadn't seen that before.
My takeaway is that we don't know yet know what the coverage area will be because all the parameters haven't been decided upon. My wild guess is that the coverage area will be at least as much as the present coverage for the sake of the ads, but multipath problems will be improved.

There are two ways to look at the reception ability of NextGen: This is my own calculation for comparison purposes only;
If the data rate remains the same as ATSC 1.0 at 19.4 mb/s, the digital cliff is reduced to 11db, a 4 dB improvement.
If you keep the digital cliff at 15db, the data rate can be increased to 25 mb/s; 5.6 mb/s more than ATSC 1.0.
However, because the video compression of NextGen is about 3 times more efficient than MPEG 2, there can be several HD streams in one transmitter.

Many thanks for the replies. It would appear at a -11db Nashville reception strength from the Rabbitearsinfo, that even with a 4 db improvement of the cliff, reliable reception with even the highest gain UHF antenna would be quite a stretch. The expertise and insight of the experts here are amazing.

Only two stations in Nashville are transmitting in ATSC 3.0 - WUXP and WNAB. They are carrying, in total, all of the programming from the partner stations. Both stations utilize directional transmitting antennas that severely limit the signals in the direction of Lake Barkley. The odds of these two signals reaching the lake location are pretty much nil, except, perhaps, under rare transient weather conditions.
All of the rest of the licensed stations in Nashville are still transmitting ATSC 1.0, just as before.
