The OVER-THE-AIR digital TV signals is full blown high def full screen TV signals... Even most campground still send you analog TV signals thru their cable hookups. You will lose out on the HDTV signal if you elect to purchase an inverter to make your old TVs to work. The digital converter will converter the HDTV signal to analog mode so it will work on your old TV set. HDTV is MUCH MUCH better to watch for us...
I never used one of the converters when the Natl Broadcast changed over to digital mode. I took my old analog TVs to the dump and replaced all of them with high def TV from WALMART. I use the 22-inch VIZIO in my popup... I use a 26-inch HDTV and a 22-inch HDTV VIZIO brand in my bigger trailer which is only setup in the back yard.
You will not need to change out the BATWING crankup antenna if that is what is being used. It will work just fine. Remember you have to go to the TV menu screen of your new HDTV and select "ANTENNA" and scan in the digital TV channels just like you do at home everytime you stop somewhere when camping. You also have to push the black button in on the TV ANTENNA WALL PLATE so the small LED light comes on which is sending 12VDC up to the preamplifier that is inside the BATWING antenna. Won't work without that... You also have to point the BATWING antenna alittle sharper to the local towns then you did with the analog TV signals but you get the hang of it pretty quick on what works...
We pick up 6-36 high def TV signals just about everywhere we camp here on the East side of the US. I like to have the 24/7 RADAR station for the area we are in to keep tabs on the approaching weather fronts. Need all the advanced notice we can get camping in our off-road POPUP setup.
Try it all out at home to see what all of the ins and outs may be for you...
My TVs are 120VAC and we use an low wattage PURE SINE WAVE INVERTER direct connected to my batteries to watch OTA HDTV when camping off the power grid. Probably a 300WATT model PSW INVERTER will be best to be able to run all of the home entertainment items when you want to ... 12VDC HDTV are not that easy to locate anymore and you pay dearly to get the 12VDC mobile versions. Not necessary to have in our situation.
