OTA reception distance decreased with HD but with better quality. GC cable was often poor quality or didn't exist. The batwing rarely goes up anymore as we upgraded the DTV sat dish to HD. Also we use a Genie receiver which retains the recordings so driving, trees etc are a non issue. We almost never use DVDs. No outside TV and the bedroom TV is original OTA and hasn't been turned on for years.
I'd label us as reverse snowbirds with 5+ months of RV travel.
Point of View: I could say that with the RV sat dish paid for sat TV cost is $0 since we move the home receiver with it's recordings to the RV.
