Does an HR22 even have 2 tuners? (2 lead connecters on back of back). It might, I just dont know. Either way, with your HR22 (SWM at home). All you need to camp is a round 18" single LNB (as mentioned above). When you set up at camp. You will need to go into menu/settings/repeat sat setup---hit dash button. let it do its thing, then change "DISH TYPE" to round 18" (Note) -- the switch will change automatically from SWM to multi. Then hit continue and let it do its thing again. After that hit "view sat signal" and go aim.
