Default what's the deal with WWBT Richmond?

I am able to pick up 5 good UHF stations from Richmond VA with my new AD HD8e.
Before I took down the old Radio Shack 2-83 fringe antenna (with Radio Shack preamp), I pointed it to true compass direction 151 and scanned for channels. The 5 UHF channels came in nicely but nothing VHF.
.
What's wrong?
.
I know that VHF signals tend to travel farther than UHF, so why I am seeing just the opposite?
.
On Wikipedia, it says that WWBT has applied to increase their power to 26kW. Does that mean they are transmitting with less power now? Every UHF station in Richmond is listed as having between 112 and 850 kW of transmit power. Why is WWBT so weak?

So so smart that's becuse THE DB8 IS A UHF only ANTENNA
Perhaps you should probably put the Rat shack ANTENNA back up
And you will receive it or do like I suggest too you 8200u and
A cm-7777AMP and rotor lol too Funny good luck.with the
DB8,and the Fcc suggests that when buy an outdoor tv antenna
They say Winegrud 8200U or a channel master combow vhf/uhf.
Outdoor tv antennas do too the changes in today's broadcasting.
Go too Fcc.com for more help when looking too buy an outdoor tv antenna.
Good luck!!

We don't know at this point. If your tuner can't pick it up, you don't know if there is a problem with your antenna system, it is too weak, you have a high noise level on VHF, or it is off the air. You would need a signal level meter to detect it if there is a signal that the tuner isn't able to pick up.

Your RS antenna is probably OK if it received UHF signals. WWBT is only one of two VHF signals in your area, but it is a weak 2Edge signal. WVPT is even weaker, and in another direction.

Have you asked anyone in your area if they can receive WWBT?

Have you called the station engineer and asked him if they are running on reduced power?



and it has terrain interference:

At this point we don't know. They could be running with reduced power.

It isn't valid to compare the power of a VHF transmitter with a UHF transmitter, because it takes more power for a UHF transmitter to cover the same area. The coverage area (and population) is important to advertisers because they want to know how many people are seeing the ads that they pay for.

VHF-High needs less power than UHF for the same coverage area, and VHF-Low, needs even less power than VHF-High.

WWBT has a construction permit for its new channel 10 transmitter that gives it a small increase in power plus some power added for vertical polarization useful for mobile devices that might receive ATSC 3.0.

I did contact the Broadcast Engineer at WWBT. He got back to me with a heat map that he saved from TVFool BEFORE the database became broken.
It was of no help because the scale was too small to effectively locate my house.
But, the best I could tell, my house is in the green/blue area, most likely in the green because I am at a higher elevation than most.
That still doesn't explain why I can't pick them up with big-ass VHF-UHF combo and a preamp.
....
I'm going to stop thinking about VHF for the next 15 months until WVIR Charlottesville makes the stupid move from 32 to 2. Then I can point something at them, LOS, and figure out my next move. 15 months is a long time. Maybe the HDB91x will be modernized by then.
.....
Did you know that, right now, there are fewer than 50 stations in the USA that transmit in the VHF-low band? No wonder Antennas Direct doesn't have a single antenna for those channels -- it doesn't make economic sense. But, as more stations like WVIR are forced down into the ghetto channels, maybe somebody will make one.

Not happening becuse I have called Antnnas Direct and yes channel master too and Winegrud.companies that make tv antennas and told me
No way are going too make a low&hi band 2/6,7/14 tv antenna.
So then I asked the question if just a low band vhf outdoor tv antenna
Would be in the making and said no and hung up on me.so I think
That the kid's today need too get into manufacturing of outdoor tv antenna's and free over the air broadcasting,too keep it going and never.let it die out

That's true, but VHF High is 7-13, not 7-14.

They are not gonna do that either.

The cable companies, dish companies, and the cellular companies want it to die out.
