Help with using Winegard's SensarPro

I started playing around with Winegard’s Sensarpro to Scan channels.

I see quite a few UHF “Real Channels” show up with pretty strong signal strengths.

Trouble is I can’t match these to the Virtual Channels (the actual channel numbers published by the stations).

I can match my four local major network channels using TV Fool and

Do the subchannels of example 4-1 4-2, 4-3, 4-4 etc follow a pattern ?

If my Main local ABC channel 4-1 has a Real Channel number of 51 (which in my case it does), would the subchannels follow suit ?.. 4-2 would be 52, 4-3 would be 53 etc. If yes, problem is a “Real Channel” 50 shows up with a very high signal strength.

Also the Sensarpro has a built in adjustable gain app. Wondering if this gain can be assigned to individual channels or just all of them.

Going to email Winegard, thought someone here might know.


Found an Android App which helps solves my problem.

Great app. “TV Antenna Helper Free”

Lists the Virtual Channels found along with the Real Channel numbers.

I still have some channels not listed, but probably have enough info now to match the unknowns by elimination.


Subchannels are all riding on one carrier signal. So your ‘real channel’ UHF 51 is carrying the program content for 4-1, 4-2, 4-3, etc. For network broadcasters, the -1 is their main channel which typically has higher resolution- 1080i/720p and secondary channels (-2, -3) are often 480i.
On antennaweb if you click a channel in their listing (it shows an RF channel and a .1 virtual channel) a window will pop up showing you all of the sub-channel assignments carried there- -1, -2, etc.

That worked, found all the subchannels.

But each subchannel would have it’s own Real RF Channel wouldn’t it ?

They are not listed there.


No, all of the sub-channels are multiplexed together on one RF channel. In a gross analogy, it’s a bit like an FM radio station having left and right audio channels carried on that station’s single carrier. For HDTV, the -1, -2, -3, etc. signals are taking up some of the ‘data capacity’ of the broadcast signal characterized as an RF channel. For sodaman_2000’s Phoenix listing above, RF channel 17 is carrying KPHO CBS 5.1 and Cozi TV 5.2.
