i've contact the installers and confirmed that they would not use diplexers and since i am in a low lying rural area they agreed to a larger over the air antenna. what else do i need to know? how fast do the channels change via the remote? how reliable is the service? i am shutting off dishnet and since i got the no contract no money down fr voom, i figure that if it doesnt work out i will fold voom and go back to dish. any comments, help would be very appreciated. thanks in advance.
