since B.W allocated for tv channel in nearly 480 MHz and each channel allocates 6MHZ B.W ,then how more than 200 channels can be viewed through one cable.
awiting for reply.
The 480 MHz bandwidth limit was for broadcast TV - the lower and upper VHF bands plus the UHF channels. When sending signals in a coaxial cable, no such restrictions apply. If the losses are not too great, many more than just 200 channels may be transmitted.
