I had cable before changing to satellite. Satellite can go out because of rain or snow but no more often than my cable service went down for unknown reasons.
Satellite outages can be a result of antenna size. I have a Winegard Carryout portable satellite antenna and a Winegard Roadtrip installed on our RV. Satellite DirecTV signal is weaker in the northwest. My installed Roadtrip antenna looses a signal when we have a heavy rain in the northwest but my larger Carryout portable antenna can pick up a signal in the rain.
A portable dish similar to a dish mounted on a house picks up a good signal, even in Canada, but a manual antenna can take time to aim at a satellite to find a signal.
RV automatic satellite dishes make locking onto a signal easy.
If you live in the southern part of the US the Winegard Roadtrip will work but if you live north you may want a satellite antenna with a larger dish.
Safe travels. JD
