(Masthead Amplifier)
Please note
The coupling torque at 7-16 connectors is 25 - 30 Nm! The tightning torque for fixing the
AISG connector must be 0.5 – 1.0 Nm (‘handtightened’).
The DTMA is not designed for permanent operation under water. Test conditions for the
IP67 rating: submerge depth 1 m, submerge time 1 hour.
It is recommended to install the DTMA’s with the antenna connectors pointing upwards
and the BTS connectors pointing downwards.
As a result of more stringent legal regulations and judgements regarding product liability,
we are obliged to point out certain risks that may arise when products are used under
extraordinary operating conditions.
In case of DTMA’s with RET-connectors (Remote Electrical Tilt-connectors according to
AISG Standard) it is recommended to mount the DTMA’s in such a way that the RETconnector always points downwards!
A downward slanted mounting position between the vertical and horizontal plane is also
allowed.
AISG Setting
The protocol of the software interface can be switched between AISG 2.0 / 3GPP
and AISG 1.1 and vice versa with a vendor specific command (depending on default
setting).
If the primary station does not support the default setting, it has to be switched over
before system start-up. Please contact Kathrein for further information.
Extraordinary operating conditions, such as heavy icing or exceptional dynamic stress
(e.g. strain caused by oscillating support structures), may result in the breakage of a mast
mounted device or even cause it to fall to the ground.
KATHREIN tower mounted amplifiers are designed to operate under the environmental
conditions as described in ETS 300 019-1-4 class 4.1E and have passed environmental
tests as specified in ETS 300 019-2-4. The homogenous design of KATHREIN’s tower
mounted amplifiers use identical modules and materials. Extensive tests have been
performed on typical samples and models.
The installation team must be properly qualified and also be familiar with the relevant
national safety regulations.
The details given on our data sheets have to be followed carefully
when installing the antennas, filters, combiners, amplifiers and
accessories.
The limits for the coupling torque of RF connectors, recommended
by the connector manufacturers must be obeyed.
Any previous datasheet issues have now become invalid.
