I would like to upgrade my home Directv to a SWM dish, DVR and receiver. I currently have a portable 18x20 3lnb dish that I use when tailgating or camping. I use my current receivers from home on these occasions. My question is will a SWM DVR and Swm Receiver work with my portable dish. I now have to change some setup settings when I go from my Slimline 5lnb dish to my 3lnb dish. I also understand that I will lose some of my HD stations since I will not get 99 and 103. SD works for me when camping or tailgating. Thanks for your help.
