9.5.3 DSC antenna
The positioning of the DSC antennas is less critical in terms of the imposed VSWR and due
to the nature of the DSC-signalling. It should be noted however, that the DSC receiver of a
VHF is likely to be temporarily blocked in reception due to high signal blocking, if the
associated DSC antenna is installed in close vicinity of a RX/TX antenna at the same
horizontal level while transmission takes place from this RX/TX antenna.
