It is very easy to bring along a tri-pod type SAT DISH. This is what we dis for a couple of years.
Our portable DISH setup had two PORTS on it so I brought two SAT RCVRs from the house on our trips. Ran two RG cables from the two SAT DISH ports with one going to the TV CONSOLE and the second one going to the BEDROOM setup. I also brought along two SAT RCVRS form home. Connected the RG cables to the ANT INPUT on each SAT RCVR and then run VIDEO CABLE from the SAT RCVR to the local TV SET VIDEO IN port.
This allowed us to use each Main and BEDROOM TV sets to tune different channels on the SAT RCVR side.
This was all condoned by DIRECTV for us to use our SAT RCVRs anywhere away from the home location. The only deal was we would lose our LOCAL TV subscription.
Our SAT units were old and most always would lose their settings when unplugged from the house 120VAC so we had to call DIRECTV to reset them or go online to do it. Just make sure you have your acct number and SAT RCVR info with you.
Worked good for us with no extra charges from DIRECTV.
Easy setup with the portable dish when you got use to the procedure.
This was back when using standard SAT TV RCVRS... Have no idea how all of this would work with the new stuff they have now...
