The following tools are required for mounting:

3.2 M ounting instructions
Antenna extensions must be mounted not only with mechanical but
also microwave-specific considerations in mind. To ensure reliable
functioning of the sensors, gap-free mounting of the antenna extension
sections in the correct position is necessary.
Note:
Gaps, additional seals or holes can cause a great many interfering
reflections. Therefore, the mechanical construction of the antenna
extension must not be changed. Extending or shortening is not
possible.
The antenna extension can be rotated at the connection points during
assembly. For that reason fasten the parts together with the screws.
Tighten the screws only after final orientation.
3.3 A ssembly steps, one-part antenna extension
Single-section antenna extensions up to a total length of 800 mm
(31.5 in) are mounted as a unit and supplied with the radar sensor.
In longer lengths, antenna extension and radar sensor are shipped
disassembled for transport-technical reasons and must be reas-
sembled on site.
Proceed as follows:
1 Remove conical protective cover from radar sensor
2 Assemble radar sensor and antenna extension in such a way that
the markings for the polarisation plane as well as the optional
rinsing air connection match
