I just got an interesting email yesterday from Camping World. They are selling a digital receiver that is capable of interconnecting with analog TV's. Supposedly it's compatible with the current version of Winegard Batwing antennas that Airstream has been supplying for the past few years.
Here is the link. Winegard Digital HD Receiver - Camping World
I think by 2009 the broadcast analog TV as we know it will end and you will need to get a converter or replace the TV. Now if you have cable or satellite you should be ok for the foreseeable future since they will not be required to change their output to your TV. Supposedly by March 2007 no more analog TV's will be produced although it will probably be some time before current analog inventories are sold out.
Supposedly Winegard also has a new batwing head that is more attuned to receiving digital TV signals although the Camping World video does note that the current batwings can receive the signals also.
I'm not sure how many stations have actually turned on to digital at this point, especially out in the more rural areas. I know here in STL all the stations have digital signals at this point. My only question would be how good the reception would be. With digital you have it or you don't, so while you won't get the typical fade in and out and fuzziness that you see in analog today, I would guess that a weak digital signal will cause pixelation or possibly seeing a picture freeze now and then. I'm also curious as to how easy the signals will propagate. Or will those remote campsites that pick up analog today, still pick up a digital?
I'll be interested in anyone who decides to spring for one of these Winegard converters. Let us know how it turns out!
