While the cable system has a high level of shield integrity, many FM tuners, receivers and radios suffer from Direct Pickup Interference (DPI), a condition where over the air signals received on the antenna connection interfere with signals received over the cable, causing interference or multipath distortion. The solution is to offset the frequencies of local FM signals from their licensed frequency. This means that the air frequencies need to be left unused, because any other signal at that frequency will receive interference.
Further, many FM receivers are unable to seperate stations closer than 0.4 mhz, so at least one blank "channel" needs to be left between any two channels.
