MW Antenna "Hordt" 1593 kHz digital (Drm), extension network (ENW)
Description:

An extension network (ENW) is needed to increase the bandwidth for digital medium wave (Digital radio mondiale = Drm).
The spectrum of the radiated frequencies must be below a defined mask in order not to distort adjacent frequencies of other radio stations.
