When the analog signal is turned off, the digital signals will continue as they are now.
Digital signals do not interfere with any other transmission.
The digital signals have been designed to cover the same type of area as the existing analog services. They have been planned so that the frequency and power of each digital transmission does not interfere with any other transmission and have generally been provided with the maximum power available.
Digital signals and analog signals transmitting from the same tower do not adversely effect signal strength
Each and every transmitter site is planned and the digital transmitters that will be provided are those that will best service each community. Operational digital transmitters are in most cases operating at their maximum power.
Most sites normally operate both the analog and digital signals and often share transmission equipment on the tower, but this does not limit the strength of either the analog or digital signal; they will not interfere with each other, nor will they “pull down” the power of the other.
Digital transmissions do not change after analog is switched off.
The normal scenario after analog switch off will be that there will be no change to digital transmissions in any way. This is because there is no interaction between the analog and digital transmissions with respect to how they operate at each site. Therefore, if consumers are not satisfied with their current digital reception, now is the time to recommend that they check their set up to prepare for switch off.
There are a very small number of sites that are known to experience some interference with the analog services; digital reception in these areas may be improved when analog switches off, but the instances of these are not significant and in most cases the digital signal at these sites have been increased to full power in preparation for the digital switchover.
