Getting my HD installed today and am curious if people in the Harford County area have any problems receiving their locals via the OTA? The installer explained to me that once the OTA is installed that I would be responsible for adjusting the location if needed. Of course they will set it up with the best possible signal, but does the OTA ever need to be moved to better the signal for different channels? *edit* Also, the installer said that I would need to go buy a protective box for the powered 4x8 multiswitch. Does anybody have any suggestions?
