I use this inexpensive TONE meter that still works like gangbusters for us...
Made by winegard...
I got one of these portable dish for my HOME DIRECTV acct. This has a compass on it and also AZ marks etc. Being flat on the bottom it sit on my truck folding hard plastic bed cover just fine. being on my truck always reminded me to store the dish before leaving the area.
This one came with a two port head for DIRECTV.
As you can see you can wind up a good couple hundred feet of RG6 antenna cable. It also mounts to to almost anything. It also folds up for storage while in route.
I would run one RG cable port to the living room TV area and the second RG cable port to the bedroom area. Here I would hookup to a SAT RCVR I brought along with me from home.
The I would hook the VIDEO OUTPUT cables of the SAT RCVR to the VIDEO INPUTS on my VIZIO 22-INCH HDTV.
Now I can watch SAT TV or CABLE/OTA TV by using the TV remotes.
