use to be a direct subscriber and then went to dish...now back to direct, where i use to take my receiver and connect with ease when i was on the road.... had the idea of taking my h24-700 in my rv when i travel...but it won't work! putting a signal meter in line does not even get a signal. however when hooking up an independent signal meter, direct to the lnb's produces a good signal. the dish i'm using is a slimline 5 ...I have reviewed several post that mention a "power inserter" what is this? is it necessary to put it in line between lnb/dish and the h24-700? I would point out that the receiver works perfectly when i'm at home and have it hooked to it's regular position.
