depends on what brand and type you're looking for.
If you can't find someone nearby and want the best (IMHO) and can drive to Houston TX and see Sats2Go. Dave is the satellite "guru" we only let him work on our '04 Country Coach. Our TracStar is still going strong thanks to Dave. TracStar gave us Dave's name and number. So if you know the brand you're going to purchase, look on their website for installers and repair centers.
