MA DAB SC
Base Station and Marine DAB Antenna with Low Weight
and Wind Load
DESCRIPTION
The dimensions of this base station, marine and receiving DAB (Digital
Audio Broadcast) antenna are kept as small as possible to reduce
weight, wind load and cost.
Despite the small dimensions the efficiency is very high.
The tapered ½ λ stainless steel radiator together with the chromed
brass housing and stainless steel corner bracket constitute an antenna
tough and ready to cope with the corrosive environment at the
masthead.
The end-fed dipole principle makes the antenna independent of ground-
plane, radials or other auxiliary arrangements.
The antenna whip should not be mounted parallel or near other metal
parts, such as windex, supporting wires etc. Free mounting and as high
as possible is preferable, otherwise the SWR and the radiation diagram
will be influenced.
