From the antenna's point of view.. The only thing that changed is the stations are harder to see (Power was reduced)
The basic Winegard Sensar (Batwing) is a fairly good VHF antenna, with UHF as kind of an afterthought.
Add the Wingman and it is a fairly good VHF/UHF antenna. (The wingman brings UHF range up to about the same as VHF)
Add the Sensar Pro indoor module (Power supply/switch/splitter and in the case of the Sensar Pro amplifier, signal detector, scanner,) and you have just about the best OTA antenna possible on an RV. (IF not the best)
The only thing better would require a tower and something like Channel Master's best witih rotor. Not something you can put on top of a motor home easily.
With the change to digital several things happened.
Many VHF stations moved to UHF (Not all) for exmaple,, VHF HIGH channel 7 in Detroit now broadcasts on, if I recall correctly Channel 41 The result is you now have a DISPLAY channel (7-1, 7-2) and a broadcast channel (The frequency they transmit on)
When I said not all, In Upstate SC. where I winterize, Channel 7 is still on 7.
Also some VHF stations (IE 2 in Detroit) moved from Low band to High band (Yup, channel 7 is what they not transmit on)
Thus the Wingman to bring the antenna up to speed in the UHF band.
The other thing is what used to be 100,000 watts may now be 25,000 (Numbers completly made up but representitive of a major decrease in power) Now digital makes up for this,, I mean you should see my collection of cards from around the world,, Digital that is, (I run 30-40 watts digital, 100 analog, but if I chat with a ham in Europe it's digital) The computer, not unlike the one in your tv or converter, has "Heard" decoded and displayed signals I could not even hear for the noise that surrounded them, and it was SOLID copy. (no dropped characters).
Thus with Digital you either get Studio Quality or total crap.
But I would fully upgrade that Batwing with the Wingman and Sensar Pro.
