Link Density mode

LD mode doubles the number of usable carrier frequencies in the available spectrum, as the minimum distance for the equidistant frequency grid is halved.

This is achieved by reducing the modulation bandwidth of the transmitter. This means that a much smaller frequency spacing between neighboring frequencies can be selected, and therefore more frequencies can be used in the same available spectrum without intermodulation.

LD mode is recommended if the following criteria are met:
  • The required number of channels cannot be achieved using the normal mode, as there may be only a small spectrum available.
  • The distance between the transmitters and the antennas is not too great.
