How does the coverage in a digital communication site compare with analog FM?
In field tests carried out by Icom and other third parties, we have observed IDAS communication coverage in digital mode up to 20 percent more than the analog communication coverage. Some reports have indicated coverage of over 80km, but as with any wireless communications system, antenna height, topography and other factors all affect total communication range. What we can say is that there is no losing coverage in comparison with analog mode. The diagram below illustrates this coverage advantage.
