3Introduction
3.1 Definition of RET
A RET is an electronic system connected to an antenna which can change the tilt of the signal
radiated by the antenna. In the past, operators used to send a person on site to manually change the
tilt. Nowadays, the RET uses the AISG standard protocol included in antennas and BTS to remotely
control the tilt.

3.2 Amphenol RET’s principle
The RET of AAS antennas comprises of a motor
to change the tilt of each array together with a
potentiometer to measure the position.
This system is preconfigured in production and
does not require a calibration when the antenna
is on the site.
The MUX board enables
the control of up to 16
motors with a single
MDCU.
The MDCU includes AISG protocol,
relevant antenna data and controls
the RET’s via the MUX board. It can be
replaced in the field.

3.3 RET manual check
3.3.1 RET with plastic tube
To manually check a Tube RET, the plastic tube need to be removed:
-Do a counter-clockwise rotation of plastic tube
-The tube is now unlocked
-Pull the plastic tube towards you to remove it from the end cap
-The RET can be now mechanically controlled by rotating the red knob by hand in a clockwise
or counter-clockwise direction
-If the RET can rotate freely then it is functional

3.3.2 RET without plastic tube
-To mechanically control the RET without the plastic tube design, apply pressure to the
relevant color coded knob (yellow, red or blue) and while pressing it inwards, rotate the RET
in a clockwise or counter-clockwise direction
-If the RET rotates freely, then it is functional

3.4 Electrical RET check
If manual intervention is not possible or not desired, RET controllers can be used. The following
paragraphs show how to use several of these tools.
3.4.1 With Amphenol Antenna Solutions PCU-4
Amphenol Antenna Solutions offers its own RET control solution. The PCU-4 tool is delivered as
a kit comprising of a computer software application together with a HW test interface with all the
necessary cables and accessories.
For electrical control, the PCU-4 kit must be connected to the antenna MDCU, (there is no difference
to connect the kit with an antenna containing old or new RETs as the MDCUs are standardized).
The PCU-4 kit contains the following :
1x Power supply cable
1x AISG cable
1x Link cable PCU-4 - Computer
1x Power supply unit
1x PCU-4 unit
- Connect the power cable to the power supply and the power supply unit .
- Connect the power supply unit to the PCU-4 unit

- To complete the PCU-4 - Antenna link, connect the male end of the AISG cable to the PCU-4
block and the female end of the AISG cable to the MDCU.
