To preserve the antenna body and especially avoid any dents or cracks in the area of
the mounting holes we would strongly recommend the following steps:
1.
Apply the combined
rubber / plastic washers
with approx. 90 mm diameter to
secure a better distribution of the pressure. Place the rubber side on the
antenna to avoid surface damages.
2.
Apply
metal washers
with approx. 30 - 40 mm diameter under head of screw/
nut.
3.
Use
self-locking nuts
or
screw locking varnish
to fix screw fittings.
ATTENTION!
Do not exceed
maximum torque of 10 NM
.
To prevent any adverse effects on the system:
-
The Antenna itself may not be mounted directly onto metal, on each side of the
Antenna, a minimum distance of 300 mm to any larger electrically conductive
structures must be maintained (essential cabling and special mounting struts
excluded). The influence of metal behind the antenna is shown in the appendices,
see section C on page 52.
-
For perfect operation of the transponder system, it is essential that there are no
interfering signals in the frequency range of 64 ±4 kHz (e. g. chopped engines,
etc.)!
-
Steel reinforcement structures located very close to the surface of the runway may
transform the Antenna energy in the ground to deviating locations in such a way
that the measured Transponder position is a faulty one, see section E on page 53.
