Karl,there is an abundance of great information regarding satelite internet and television reception on the
DataStorm Users Forum
Simply click on the above link and browse through the subject titles that interest you.
Many folks there,including myself until this past Friday,were registered forum users and didn't have a dish yet. I found many of the answers to my questions over there.
Once I got my "comfort level" I made the purchase.
Since my coach already had the "in motion" television antenna, I didn't have the need for a BOW antenna....BOW stands for "bird on wire",which is essentially something that attachs to your internet dish arm to receive the television signal.
My install pics are in the photo section of iRV2 and my present location is on the link in my signature....
Be aware that I opted to purchase a larger dish than you'll need for the "basic" rate and service plan....
Let me know if I can help....there are several iRV2 posters here that are much more educated in this than I.....John Canfield is one that comes to mind....
