You are picking up a digital signal! HDTV is just a picture format that rides on the digital signal.

While HD is a marketing name, it is different that the old analog signal we used to get with rabbit ears. Digital TV signals fall in the UHF band. It used to be you could get VHF antennas, or the optional, more expensive VHF/UHF combination. While the regular Sesar will capture UHF, it doesn't do it great. When I installed (thats a joke, it's a 5 minute swap) my Jack, I went from 5 channels to 25, and far less pixellation. YMMV, but I like my Jack, and found an improvement.

Carr, there is some incorrect information in your post.

While TV broadcasts are mostly now digital (some low power local stations were not required to switch to digital), they do broadcast digital signals on both the VHF and UHF bands.

The "Old" Sensar antenna has directional VHF elements (the Bat Wing) and a circular UHF antenna (located inside the white amp box). That made the VHF directional and the UHF omnidirectional. However, the VHF portion could pull in stations from further away than the UHF staions.

If an analog station was too far away it still came in it just was snowy due to interference. With a digital signal, the signal strength must be high enough to "read" the data being carried on the carrier wave. If not you get drop outs (pixelation).

www.antennaweb.org web site will tell you the direction to the signal towers and whether that digital station is broadcasting in VHF or UHF.

The Wingman acts as a magnifying glass and "focuses" the UHF signal on the circular antenna in the white housing. That makes the UHF antenna directional as well. When you want to aim the Sensar or Sensar with Wingman, you just think of the antenna as an aircraft flying towards the broadcast tower. The white housing (or Wingman Fins) is the cockpit and the bat wings are the wings of the aircraft.

The protractor mod is a simple mod you can make that will allow you to aim your antenna directly at the correct tower for the station you are watching without leaving the camper once you set it up.

Thanks for the info Herk. Some folks have had good luck with the Jack, other folks not so much. I just took delivery of a new V-Lite with a 32 inch Toshiba. I tried the standard antenna first and got 5 channels A 10 minute swap to a Jack got me to 14 channels that were watchable. I did read somewhere that new HD signals were in the UHF band. I'll look for the link if there is an interest and hyperlinks are allowed on the board.

Digital is on both VHF and UHF. If you go to www.antennaweb.org and put in a zip near a major city you will find HD digital on both VHF and UHF bands.


Here is a Philadelphia Pa product,
Note there are 2 VHF HD digital channels.

Thanks everyone. Very informative. I'll most likely buy a Wingman this time around.

Tomorrow is delivery day! Going to be happy to have this deal behind me. Now we CAMP!
