If you already have an account with DISH or DIRECTV its pretty easy to carry a portable tripod dish with you along with one of your spare SAT RCVRS.
It is very easy to find the SAT position and with the portable dish and you can receive the standard TV format...
Be sure to carry with you your account number and other SAT TV INFO including theoir 800 number. In my case my SAT RCVR loses its setting when I unplug it from it from the house and when I get setup again any where in the US I usually have to call the SAT PROVIDER and get them to reset my signal. You can do this ON-LINE as well if you have the account number and the SAT ACCOUNT ACCESS code...
I pasted an envelope to the SAT RCVR I was carrying with me so I would always have it with me. This is all legit with your SAT PROVIDER and there is no charge or anything like that if you already have an account with them.
In my case I do lose my LOCAL TV STATIONs. These require you to be in the same ZIP CODE area to receive them...
I just use one of those BIRD WHISTLE SAT TV locator and then run the RG cable into the trailer and connect it to the SAT RCVR ANTENNA INPUT. Works like gang busters for us...
I did this alot but when the NATL BROADCAST changed over to DIGITAL TV a few years ago I finally stopped bringing along the SAT TV items as the Direct TV OTA signals from the local towns turned so good for me picking up many full blown HIGH DEF TV signals just about everywhere we went to her on the East side of the US. The HDTV from the local towns is much better quality than the STANDARD mode SAT TV signals. We use the RV Trailer BATWING crank up OTA antenna to pic up these digital HDTV signals with great success... These are only the standard BROADCAST TV signals along with a bunch of movie channels and alot of the OLD TV programs like Gunsmoke etc... They also usually have a 24/7 RADAR channel which is next to have available when camping... The NATL BROADCAST HDTV digital TV stations is FREE to the public of course...
This is a couple of easy to do options for you wanting to watch TV when in camping mode...
Probably a good idea to try all of this at home first so you can learn all of the little things you need to know before getting out in the boonies somewhere...
