As already explained in detail, very good reception is only possible if the antenna is mounted on a conductive metal surface. You can glue these roof bonnets directly onto the roof if there is a possibility to lead the cables into the interior of the vehicle under the roof bonnet.
First, the antenna is screwed to the roof bonnet, then a roof grommet is drilled and the 30 cm long cables of the antenna are led into the vehicle interior.
For bonding and sealing the plastic roof bonnet we recommend the bonding set (DN-SetMS5). This item is not included in the delivery and must be ordered separately.
Please note that in case of service, the bonding of the roof bonnet must be loosened in order to replace the antenna!
About the product:
Groundplane for GRP roof superstructures. The plastic roof cover with internal metal plate provides the necessary counterpole for the optimal function of car radio antennas on GRP roofs.
The roof bonnet is glued. For the bonding work, we recommend the optional DEKALIN bonding set DN-SetMS5.

Note on our low-loss cables:
Low-Loss cables (...low loss cables) are the cables with the best electrical properties for the loss-free transmission of antenna signals. Our Lowloss cable series has the best conductivity values and thus the lowest cable resistances. They are achieved by using tinned strands for the inner conductor (7*d=0.25mm), for the shield (42*d=0.11mm) and an additional aluminium foil between the PE dielectric and the shield. Only high-quality Fakra plugs and sockets from Rosenberger are used. They have an excellent finish and fit due to a special punch-bend technology of the Rosenberger company(Fakra-SF).
