Radio Datasheet 7186 VET Antenna Installation - Guidelines on use of Kathrein Handheld PCA and Software
This datasheet is compiled and owned by Radio Engineering. Date of last update : 22 September 2010.
SUMMARY: O2 (UK) deploys a number of VET antennas in the network build programme.
These antennas require special procedures and tools when deployed, and when
future optimisation is required. Currently all VET UMTS antennas are
supplied by Kathrein, Jaybeam and Powerwave and Argus. This Datasheet
defines the installation and software configuration of VET antennas using the
Kathrein handheld Portable Control Adaptor (PCA), and also gives details for
configuring the NSN MHA (AISG WMHD version). It should also be noted that
use of the old Sigma VET control software is not longer approved for use on
any O2 antenna system.
This Datasheet (V3.3) has been updated with information regarding VET
Motor configuration for UMTS 900 deployment (Page 8, Paragraph 7)
Target Audience This Datasheet is intended for use by anyone required to install or work on O2 UK
RF antenna line systems.
General Information VET installation work may only be performed by suitably trained personnel. All
rigging engineers must have access to the correct software tools and fully understand
all commissioning and set up procedures prior to working on any AISG controlled
antenna or MHA system
When installing VET antennas, the following items will be required, in addition to
the normal antenna installation tools:-
1. Kathrein Handheld PCA box, part number 860 10046, as shown below
2. VET Control cables of required length (See “VET Control Cable” section
below)
3. VET Cable termination box (See “VET Cable Termination Box” Section
below)
4. Laptop PC with Kathrein Version 2.1.1 PCA Software, with Device Data file
version 2.02. Note: It is important that the software versions given are used, as
antennas currently being deployed by O2 will not be able to be controlled by
earlier versions of software.
5. A short VET control cable to connect the termination box to the controller

VET Antenna Use A VET antenna will generally be the standard antenna type deployed, therefore the
only use of fixed tilt antennas are on legacy deployments and when needed for
maintenance replacement. Although VET antennas will be deployed, a VET motor
and associated leads may not always be required. The guidelines given here are to
assist Radio Planners and build contractors as to when it is appropriate to deploy
antenna which can be remotely tilted
In general, an antenna must be deployed as remote tilt unless the antenna may be
manually optimised using the following guidelines:-
1) No outage is required for any antenna on site
2) The antenna is accessible by a person who is not a qualified rigger
3) The antenna can be accessed with no “access fees” payable i.e. sites such as
Arqiva often incur a charge for access. In this situation, remote VET antennas
should be deployed, even if they follow the above guidelines, as long as the
VET box can be accessed without incurring charges.
In general, this will only apply to rooftop sites where the antenna may be easily
accessed by a non rigger person
VET Control Cable A VET antenna installation will be any combination of single band, Multiband or
Triband antennas on any given site. Each antenna may either use a separate control
cable, or 2 or more antennas may be “Daisy chained” together, using control cables
looped from one antenna to the next, with one main cable back to the BTS
equipment.
Antennas from different manufactures, and of different operating frequencies may be
mixed on site, and daisy chained together onto a common VET control cable
The maximum cable length to any antenna should not exceed 150m. If daisy
chaining antennas together, installers must ensure that the total control cable length
doesn’t exceed 150m (Note: There is not an actual firm cut off point for the length of
the VET cable, and will depend on site specific conditions, however, installers
should note that problems may be encountered if the run exceeds 150m)
Note: Argus antennas, being deployed by O2 from January 2010 for 6 sector
working, don’t have the facility to daisy chain antennas, as they have one AISG port
only. When deploying Argus antennas, the Kathrein AISG splitter box, Part number
860 10002, should be used, as shown below.
Kathrein VET Cable Junction box (Approx. 91 x 103 x 72mm)
Note: The Kathrein junction box must be used in the correct orientation, with
the AISG connectors situated at the bottom, facing downwards.
Tower type installation: The standard configuration would be one master control
cable running from the termination box at the BTS equipment location and up the

tower to the AISG port of the first antenna. The other antennas are then daisy
chained as required. The unused AISG port of the last antenna must be sealed by a
cap or other appropriate method. This is shown in Diagram 1 below. Use of Kathrein
Multiband or Triband antennas will require that a short (typically 500mm) jumper
cable is used to daisy chain the UMTS and GSM motors together.
Diagram 1. Daisy chained antennas
Roof type installation: For rooftops, it will often be more appropriate to use
individual control cables for all antennas. In this situation, a single cable is run to
each antenna AISG port, and the unused AISG connector sealed by a cap or other
appropriate method, as shown in diagram 2 below.
Diagram 2. Individually connected antennas
Junction box: Where appropriate, or when deploying Argus antennas with one
AISG port only, rather than running 3 main VET cables back to the termination box,
a Kathrein 3 way junction box (Available from Kathrein UK, address as previously,)
may be deployed at a suitable location in the VET cable run to connect all 3 VET

cables, and a single cable then run from the junction box to the Termination box, as
shown in diagram 3 below.
Diagram 3. Individually connected antennas with Kathrein Junction box
In some situations, it will be appropriate to use a mixture of the above methods.
When for example 2 antennas on a roof top are closely spaced, then these antennas
can be daisy chained, and a third antenna which may be somewhat further away, will
have a separate control cable.
Control cables and VET termination boxes are available from the following:-
