I have been doing telecommunications for many years and I know that when the Truth Is Not Presented Up Front!!! . . 3 Tv's through out the house , connected Via Splitters , The 'Via Splitters' is a tell tale sign of problems. One splitter connected to an other splitter connected to an other splitter connected to an other splitter connected to an other splitter connected to another splitter and etc.. . . . ONE 3 Way Splitter with the with the input connected to the antenna and each of the 3 out puts will have a Single and Continues RG-6 coax cable run to each Tv location. .
http://www.solidsignal.com . . the Channel Master CM3213.. Next look at the Virtual and Real Channels , WTXF Virtual 29 is Real Channel UHF 42. . Is the Tv antenna aimed correctly at the Tv Transmitters?? Or is the UHF end and UHF reflector turned in the oppisit direction of the transmitters north and west of Philadelphida. . And what about the double rescan at dtv.gov. . GET YOUR SITUTAION CORRECTED FIRST !!!!. . I believe that you are still leaving out some facts about your situtation. . CONNECT -->ONE<-- TV TO THE ANTENNA WITH NO SPLITTERS , Now what does 17 and 42 look like???? .. And a scanner is a device that receives but does not transmit. .
