IMPORTANT
It is recommended to tighten the SMA antenna connector on the interface firmly, but
without damaging it (tightening torque 0.9 Nm).
3.8.4
Optional external antenna assembly
We recommend the use of the high-gain ANT2/4G-HG antenna if the planned antenna installed does not
guarantee an adequate signal level due to the position of the MEDEA control unit.
The ANT2/4G BM stylus antenna can be used as an alternative to the PCB antenna supplied with the
2G/4G modules for the ABS box.
3.8.5

IMPORTANT

not
powered
