Tv antennas and Tv reception
Something else you need to know. There are Real Digital Tv Channels and Virtual Digital Tv Channels. As an example , KCBA-DT 13 = the Real channel is 13 , 13 is what is received by the antenna and the tuning device. The Virtual channel is Not a real channel it is a virtual channel 35.1. A few tuning devices can display the Real Channel , most can not and so displays the virtual channel. The main reason but not the only reason for virtual channels is the channel number before the digital conversion was as an example 35. The tv station kept the now old 'legacy' channel number of 35 even though the tv station is now transmitting on 13. Some tv stations choose to stay on the same channel , as an example , KSBW was transmitting analog signal on channel 8 , and when the tv station switched to digital the tv station switched off the channel 8 analog transmitter and switched on the channel 8 digital transmitter. And here is a mind twister for you , the Real channel 8 is the real 8.1 channel and the 8.1 that is listed as the 8.1 virtual channel is a virtual channel. Real is real and virtual is virtual.
