I have a brand new 2018 Coachmen Concord and it came with a Wally receiver, King Tailgater satellite antenna, and a King Jack OTA antenna, without an auto signal finder. My question is: Are these the devices I can purchase for an RV? I want to increase my chances of great OTA, satellite and Internet chances. Also, can I replace the wally box with a hopper to be able to view my DISH ANY WHERE app "Live"? If not, please advise the equipment thats available to make that happen.
