We have been RVing over 3 decades and initially used our rig's OTA antenna, works okay in large cities, just unreliable reception anywhere else, and that's the problem as we don't do much RVing in major cities. Even with a good OTA signal, channels were limited and all commercial driven, makes it difficult to watch marginally good tv with all the interruptions from sponsors. Practically 100% of RVing back then was with our kids, not an issue as VHS and DVDs made every night a movie night, kids had a blast and DW and I could have some time to ourselves.
We have satellite service at home and as most of our camping was on weekends I was missing out on keeping tabs on scores throughout the day. Again, this is going back a couple of decades, we started to bring along a spare bedroom receiver and manually setting up Directv satellite antenna, only one satellite back then and acquiring sat 101 was easy peasy. The advent of HDTV and having to acquire 3 sats did not pose much of an issue, dealing with the skew parameter only adds a couple of minutes to our pointing routine, overall a 10 minute process to begin downloading program guide.
Today there are more options, plus OTA has several dozen channels to peruse making it a more viable although we rarely use it. We do occasionally stream video content and still use DVDs here and there, but our bread and butter is satellite tv, and all the satellite recorded programming on our DVR. We have Dish and their mydish app works great, makes it easy to change local channels to your location. There are many automated satellite acquisition domes available, all we do now is plug rig into shorepower upon arrival, we have same channels we have at home all before we have finished setting up rig.
