satellite tv

[wingnut60]

Need some advice/help from all you satellite tv experts--
I have the Winegard Carryout receiver and it works well now that I have gotten used to how it needs to be connected to my Dish TV DVR receiver.
However, we have found that we cannot get the major networks when on the road--we can only get the major (called 'local' channels by Dish) when in promimity to DFW area where we live. Dish says we can only get 'local' channels by changing the billing address, something not practical as we are only out 2-3 weeks at a time.
Is there a solution to this situation--can I actually somehow get the major channels when traveling and in a single location for a week or so? Is DirectTV any different?
I am getting fed up with Dish but don't want to change anything if there is no benefit to the change.
Any help will certainly be much appreciated--it is irksome not being able to know what is going on locally when in one place for several days.
Thanks,
Joe
