Safety Instructions
The antenna and its accessories are not toys for children to play with!
Keep any spare installation accessory items away from children (danger
of choking on small parts).
Wall mounting: Before drilling the holes, make sure there are no
electrical cables in the wall.
Danger to life from electric shock!
• Pay attention to exposed wires, if they are routed close to the
installation location. They pose an acute danger to life if touched!
• Never work on antenna systems when a storm is approaching or
during a storm. Danger to life!
The antenna may only be operated in the 5 to 25 Volt range.
Electronic equipment is not household waste. In accordance with
directive 2002/96/EC OF THE EUROPEAN PARLIAMENT AND THE
COUNCIL of 27th January 2003 on used electrical and electronic
equipment, it must be disposed of properly.
At the end of its service life, take this unit for disposal at a designated
public collection point.
Earthing and lightning protection measures may only be carried out
by specially trained electricians, otherwise work may be of inadequate
quality! When mounting on antenna masts, your life and health may be
in danger! So please note the following points:
• Always wear a properly fitted and intact safety harness when climbing
roofs or other locations where you are at risk of falling!
• Make sure the roof is able to hold your weight. Never walk on crumbling
or unstable surfaces! Wear firm, non-slip shoes!
• Ladders or other climbing aids used must be in good working order.
Do not construct wobbly „towers“ to climb up!
• If passers-by are at risk from falling objects during installation work,
you must cordon off the danger zone!
• The antenna mast must be properly earthed in accordance with
DIN EN-60728-11.

General
Intended Purpose
The active antenna is suitable for outdoor mounting in order to receive
digital terrestrial TV and radio signals in the VHF (band III) and UHF
(band IV, V) bands, provided there is an adequate signal level.
General Points on DVB-T Reception
In areas of low or excessively high signal strength, interference-free
reception is not guaranteed under all circumstances. If the signal
level is too weak, a mast-mounted directional antenna installed on the
building‘s roof should be used. In close proximity to the transmitter,
reception may be impaired by excessively high signal levels. In such
cases use an indoor antenna, such as the BZD 30.
Reception may also be impaired by other factors. Critical installation
locations are:
• on steel-reinforced concrete structures
• on enclosed metal structures or cladding etc.
• in close proximity to transmitting electronic devices (such as mobile
phones).
Essential Accessories
Reception of DVB-T signals requires a DVB-T-compatible receiver, with
remote feeding (5 V) via the coaxial cable or an external remote feed
power supply unit (5-25 V).

Installation, Connection and Setup
To fit the F standard connector:
• Slot the cap onto the cable (see figure 1).
• Strip off the outer sheath of the cable, making sure you do not cut
through the braided shield (dimensions in mm) (see figure 2).
• Carefully bend back the braided shield (see figure 3).

Pre-assembling the Cable
• Expose the inner conductor as shown in figure 4 (dimensions in mm).

Installation, Connection and Setup
1. Connect the antenna to the DVB-T receiver by the coaxial cable
provided. You can install the antenna regardless of the polarisation
of the transmitted signals.
• Screw the F standard connector onto the matching antenna
socket. Push the cap over the F standard connector until it locks
into the antenna housing.
• Plug the IEC connector on the rear of the receiver into the opening
provided for it.
2. Connect the receiver to the TV set (consult the receiver manual for
more details) and switch the receiver on. Set the TV to AV mode, if
it does not do so automatically when you switch on the receiver.
3. Check the DVB-T receiver‘s Setup menu to make sure the power
supply to the antenna is connected via the coaxial cable.
4. It should now be possible to receive DVB-T programmes.
Connecting the Antenna and the Receiver
• Before fitting the F standard connector, make sure no strands of the
braided shield are touching the inner conductor. This could cause a
short-circuit. Carefully twist the F standard connector onto the end of
the cable until it is firmly in place. The inner conductor should protrude
a maximum of 2 mm out of the connector. The inner conductor must
not be bent! (figure 5)
The quality of the received signal also depends on the cable
assembly!

Installation, Connection and Setup
Try to receive at the most suitable antenna position - preferably where
you are intending to fix it later. Pay attention to how the cable is laid.
The antenna can be swivelled in order to improve the received signal.
To align the antenna:
1. Slacken the clamp screw using the Allen key provided.
2. Swivel the antenna in 30° increments until the reception is
satisfactory.
3. Tighten the clamp screw, making sure that the retaining plate locks
into the antenna housing.
If optimum reception is not possible, test the antenna at a different
location facing towards the transmitting antenna and repeat the above
steps.
In close proximity to the transmitter, reception may be impaired by
excessively high signal levels.
Optimising with DVB-T Receiver
Some receivers feature on-screen signal level and quality displays,
allowing you to optimise the antenna positioning still further. Refer to
the operating manual for the receiver concerned for details on this.
Cleaning
Use only a damp cloth to clean the antenna. Do not use aggressive
or abrasive cleaning agents, as they may damage the surface of the
housing.
Never immerse the unit in liquid.

Installation, Connection and Setup
The necessary fixings for wall mounting are provided with the antenna.
Once you have found the optimum reception position for the antenna
you can drill the holes for the wall bracket.
Be sure to mount the antenna with the cap and cable facing
downwards.
Wall Mounting
Before installing: Before drilling the holes, make sure there are no
electrical cables in the wall.
Danger to life from electric shock!
Mast Mounting
The product package includes the fixings necessary to attach the
antenna to a mast. Bolt the two supplied worm drive hose clips to the
mast. Do not yet tighten the bolts fully. The mounting bracket of the BZD
40 has lugs at the top and bottom which engage in hose clips to mount
and secure the bracket. Rotate the antenna until you get optimum
reception. Once you have found the optimum reception, you can tighten
the worm drive hose clip and the clamping screw.
Make sure the antenna is mounted so the cap and cable are pointing
downwards.
19
Optional Mounting Position
The range of possible mounting positions of the antenna can be
extended by modifying the mounting bracket.
When modifying the bracket, first remove the clamp screw and the cap
and cable as necessary. Then remove the bracket and refit it the other
way round. In doing so, be sure to slot the bracket in at the bottom first
before fixing it back in place with the clamp screw.

Balcony Mounting
The necessary fixings for mounting on a balcony are provided with the
antenna.
Once you have found the optimum reception position for the antenna
you can drill the holes for the balcony mounting bracket.
Be sure to mount the antenna with the cap and cable facing
downwards.
20
Installation, Connection and Setup
Cap should be facing downwards - horizontal mounting permitted.
When laying the cable, make sure it is always initially facing downwards.
This will prevent rain from dripping in to the antenna through the cap.
Incorrect Installation
Pushing the Antenna Cable through the Wall
If you are routing the cable to the outside through the wall, after
pre-assembling the cable, optimising the antenna alignment and
mounting it, as described starting on page 5, carry out the following
steps:
1. Remove the F standard connector
2. Detach the cap from the cable
3. You can now route the cable out through the hole in the wall from the
inside
4. On the outside refit the cap on the cable, as described on page 5
5. Screw the F standard connector back onto the cable
Before installing: Before drilling the holes, make sure there are no
electrical cables in the wall.
