It depends on the service you have at home...if you have DVR set up on any receivers, those units must remain in their installed locations (same jack they were assigned to) in order to work properly. We have 4 receivers, 2 of which are dedicated to certain locations in the home, one remains in the RV all the time and is not a DVR unit. Since it sits idle a lot it must be activated by phone when we travel.
We went a different route for our service. Since we were once fulltimers we ordered the "mobile/RV" service to use in the MH years ago. Once we built our barnhome DirecTV didn't mind if we kept the service so we have east/west coast network channels all the time at home and in the RV.
Our so called "local" channels if we'd stayed without mobile,would have been out of Denver, 300 miles away so it is no matter to us losing those networks in our home time zone. We actually like having 2 time zones to catch our favorite shows to view and DVR. We don't watch those news shows. We get our local news from our local newspapers and radio. There are other sources for national and world news.
There was a time when DTV customers could just take a box along all over the country and still get the same same local networks stations. For the most part that is now not possible. The system knows where you are so once you are away from your local spot feed area those channels will probably go away.
When it is mentioned you lose "local channels" it means ABC, CBS & NBC affiliates. You should be able to receive other networks Disney, FOX, RFDTV, ESPN, History, AMC --whatever is in your package.
Give DirecTV a call and ask them about your options.
