...... I have a small house on the coast (actually a fishing camp) two hours away ......
If the vacation house is only two hours away, it may very well still be in the same spot beam your permanent residence is. If so, just pay a dealer for a dish install at the vacation house, cart the receiver back and forth, and continue watching your home locals.
Different local markets share the same spot beams.
Places I travel with the motorhome cross into different TV markets, but use the same spot beam as my home locals. I just leave well enough alone and keep my home locals and use the motorhome TV antenna if I want the area stations.
