We had DirectTV for years, but when the bills started pushing $200, we finally unplugged. Turns out we could get all the cable channels we care about over the internet with "DirectTV Now" for $40/month. We added an antenna in the attic for the locals -- and picked up about a dozen oldies channels we never knew existed. We use an Amazon Firestick in all the TV's, which got rid of all the satellite boxes and wiring. And we added an over-the-air DVR that rebroadcasts over wifi to the firesticks, so we even get live antenna TV anywhere in the house without any wires. The total conversion cost about $1000, which paid back in a few months.
We tried taking a Firestick on the road with us last time out, but discovered that the free WIFI at the RV park didn't have the bandwidth. It worked fine with one of our cellphones set up as a hotspot, though. For the savings on our TV bill, we could upgrade our cell phone service to unlimited and still come out ahead, but even that weekend's TV watching didn't bust our limit that month. For part-timers like us, it might not be worth it.
Instead of spending the bucks for a satellite antenna, you might look into the cellphone hotspot/firestick idea, unless you typically camp where there's no cellphone service.
