250' og RG-6

Hard to believe the signal which has traveled from a geosynchronous bird, some 22,000 miles away in outer space, to your antenna would be at all shy about traveling another 250 feet to reach the receiver. but I don't know that much about how sat tv actually works, just the broad strokes.

In our personal experience you should be able to make that work without an amplifier if you use high-grade RG6 and minimum connections - don't connect a bunch of shorter lengths. You will be more subject to rain fade but in SC you are close enough to the satellite I don't believe you will have a problem in good weather. It doesn't hurt to try, you can always add an amplifier. I was able to get good HD from NE FL on a Slimline antenna and 240 feet of cable. That same combo didn't work in the Michigan UP - too far from the satellite.

Back when I was using a portable SAT DISH setup I had two runs of 150-feet of RG6 running to the trailer with one run to each of my two TV's. Didn't have any problems with that.

The problem I was always fighting doing this was what to do about thief control of my SAT DISH when we left the area unattended.

I usually would setup on the flat area of my hard plastic covered truck bed with my dish and this would always make us move the dish inside the trailer when wanted to leave the camp site. Wasn't too bad having to setup again when we returned... We already knew where to point it...

When the NATL BROADCAST changed over to digital HDTV a few years back we stopped bringing along our SAT DISH and now get our TV fill by using the trailer BATWING antenna picking up free CLEAR TV from the local towns. HDTV was better to watch using this setup then the standard SAT TV anyway...
