4.1 GENERAL ANTENNA
The external antenna
DC2041
, which is delivered with all DECT-Com II main units, should normally be mounted on the main
unit together with a plastic ring (see 4.1.1 UNIT FUNCTION INDICATORS below).
4.1.1 UNIT FUNCTION INDICATORS
A package
DC2048
with 3 differently coloured plastic rings is enclosed in the box of each DECT-Com II main unit. The rings
are meant to seal around the antenna connector, but also to indicate the function of the unit; for instance a red ring for a
base unit, a green ring for a portable unit and a black ring for an “other” unit.

The omni directional antenna
DC2046,
with magnetic foot, can replace the external antenna
DC2041

improve communication with portable units outside of a vehicle if the base unit is placed inside.
Notice
: No other external antennas than DC2041 or DC2046 are allowed for use with the DECT-Com II system.
