Their statement about having satellite television is a bit confusing, since every area in the continental US has satellite television available if you have a satellite dish and a satellite receiver. What I think they mean is that they have cable TV whose source is satellite - which doesn't make much difference to the user. What you'd need (assuming my guess is correct) to connect to their system is just a length of RG-59 or RG-6 cable. This is the standard round cable used for any cable TV hookup and is available at a Lowe's or Home Depot. You'd use this cable to connect to your TV cable input - probably on the outside of your trailer. You'd probably want to by a length of about 50 feet or so, with the connector ends already attached.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
