The compact portable dishes sold at Camping World, etc for Dish and 'FTA' are not suitable for FTA linear signals. Save yourself A LOT of grief. The dishes I mentioned catch the signal quickly (by comparison). I helped a fellow traveler in Casa Grande, AZ set up a 30" dish. Mine locked in less than 8 minutes - his took me almost 40. I have set up from Langley, BC, south to San Diego, then East to CC TX and on to Orlando FL, up to TN then meandering NW through GA, IL, NE, ND, MT, ID and home (39 states on our map). I carry 1-50', 1-25',3-10' and 1-6' RG6 cables plus about 10 barrel connectors. I also carry a cable making connector kit, but have not used it on the road for myself for 3 years.
One other thing! I am frugal.... $ time Energy. I have all my bolts and nuts replaced and use 1/4 -20 hardware = 2 combination box / open end wrenches and a 1/4 drive socket are all I have to carry and spray painted them red and blue so they show up where ever I drop them! (7/16th I think).
