Thank you for the additional details. It is getting more complicated, so I will need to ask more questions and study it further.

If you just wanted WSMV from Nashville and only UHF from Huntsville, it would be easy to combine the two antennas.

My situation is we like the Nashville market news mainly WSMV real channel 10 which we get through Dish. We want to get rid of the Dish bill.
Now I understand why WSMV is so important.

If I were there with you, I would want to buy a 30-2476 VHF antenna and a preamp to see if WSMV is even possible. It would be a $35 gamble for the antenna.

We have a UHF on a tower pointed towards Huntsville
What UHF antenna are you using?

How many TVs are you using?

So that would be a Winegard 7698p for Nashville mounted below the existing UHF (for huntsville). Could they both be on the same amp and coax or would they need to be independently wired and amped and use a A/B switch in the house.
They could be on the same amp and coax IF you only wanted WSMV from the 7698 as a VHF only antenna and only UHF from the Huntsville antenna.

But if you want VHF and UHF from Nashville and UHF from Huntsville, that creates a problem, because it is difficult to combine UHF from two antennas aimed in different directions.

You would need an amp for each antenna and a separate coax for each antenna. Down below you could have an A/B switch to select which antenna is needed. This creates a problem if your TV can't add a channel after scan; you would need to rescan after changing the antenna switch. The way around that is to connect the main antenna to the TV antenna input, and connect the second antenna to a separate tuner with its output connected to the TV aux input.

The Nashville channels we want in order of priority are
WSMV real 10
WKRN real 27
WTVF real 5 and also 25 (only shows 5 on tvfool)
Just real 10 is easy to combine with UHF.
Real 27 would be hard to combine with UHF from Huntsville.
Real 5 requires a BIG VHF-Low antenna. It is as long as the 7698 and much wider.

I wonder if WSMV has any plans of moving to UHF?
I doubt it. The FCC is cutting back UHF from 14-51 to 14-36. The channels from 38 to 51 have been auctioned to cellular companies. The listing indicates it will stay on 10.

I looked at the 7698 its a montster at 14 ft long so I am a little concerned about that.
Weak signals require antennas with more gain. Antennas with more gain are bigger. A preamp can't compensate for an antenna that is too small.

What about that HDStacker is it a good option?
I'm not impressed with it for your location.
