Antenna
The antenna features different connectors. These are NOT compatible with previous
RydeSmart transceivers. Switching to FAKRA connectors will improve reliability and
eliminates the possibility of over tightening of breakage. Connecting and disconnecting is
done without tools.
Antenna Placement
Glass Mounted Combo
antennas should only be mounted on the passenger side, right edge
of the windshield.
The Glass Mounted Combo antenna can only be used on vehicles with slanted
windshields where the surface of the glass is angled at less than 60 degrees.
Do not use on vehicles with racks that overhang the windshield.
Approved Locations:
On the top of a flat roof with no obstructions
Attached to an approved extension to lift the antenna above obstructions (must still
have a grounding plane).
Hidden Antenna Placement
In the Headliner
The trim in the area the antenna is to be installed needs to be removed and
the headliner lowered to accommodate the hidden antenna.
Large side of antenna should face metal of vehicle.
Once the hidden antenna is in place do not raise the
headliner in the event the antenna needs to be moved for
maximum coverage.
Once the antenna is installed in the best location, affix a piece of double-
sided tape to hold it in place.
Verify the location of the antenna will not create a bulge in the headliner.
