1.0 INTRODUCTION
Thank you for purchasing the STRONG SRT ANT 12 ECO DVB-T/T2 antenna. This antenna has been specially
designed to receive digital terrestrial signals from the air. It can be connected to any Digital Terrestrial
Receiver (DVB-T/T2), and is designed for indoor use only.
This DVB-T antenna is an “Active type” antenna, it has a built-in low noise amplier that amplies the
received signals for better performance.
We recommend you to carefully read this user manual before you install the antenna, this will help you to
get the best performance out of your antenna.
Specications:
Frequency range: VHF 47~230 MHz, UHF 470~870 MHz
Gain: 45 dB for VHF and UHF
RF Output Impedance: 75 Ohm
Power Supply: 5 V DC / 40 mA via antenna connector of the digital terrestrial
receiver or
12 V DC / 250 mA via external 230 V AC to DC adaptor
Special Features:  Built-in Low Noise Amplier technology
 High directionality: optimised pointing to the transmitter and
reduced pick-up of disturbing signals

3.0 SAFETY NOTES
 Use only originally supplied accessories.
 Before you make any connections: disconnect your equipment from the 230 V main power to
avoid electric shocks during installation.
 Short circuit in the coaxial cable MAY permanently damage your Digital Receiver.
 Never install the antenna outside your house or in humid rooms such as bathrooms.
 Never use AC adaptors with wrong specications, this MAY permanently damage your
antenna or Digital Receiver. Always check voltages and polarisation of the adaptor before
connecting it.
4.0 CONNECTING THE ANTENNA
1. Check if the broadcast in your country is horizontal or vertical polarized.
2. Click the antenna in the plastic holder as shown in the pictures

 (H - Broadcast) antenna mounted H
 (V - Broadcast) antenna mounted V (Upright)
3. Disconnect your Digital Receiver from the 230 V main power.
4. Connect the supplied coaxial cable to the antenna: carefully press the inner lead of the cable
into the Female-F connector at the back of the antenna. Turn the covering nut clockwise
with your HANDS until it is xed.
5. Connect the other side of the coaxial cable to your Digital Terrestrial Receiver. Normally
the input connector on your receiver is marked as “ANT” (in) or as “RF” (in). Refer to the user
manual of your Digital Terrestrial Receiver.
6. Connect your Digital Receiver to the 230 V main power.

5.0 INSTALLATION OF THE ANTENNA
A: To power the antenna with Digital Terrestrial Receiver
1. Turn on your TV set and turn on your Digital Terrestrial Receiver.
2. Press the “MENU” button on the remote control of your Digital Terrestrial Receiver. Check
in the Set Up or Installation menu of your receiver if the antenna power is set to “ON”.
(Normally this is indicated in the menu as ANT power, Ext antenna power or Active antenna
power.) Refer to the user manual of your Digital Terrestrial Receiver.
3. Select in the menu of your receiver the eld that shows the signal level indicators. (Normally
you can nd the signal meter in the Channel Scan eld of the menu.)
4. Now optimise the signal strength by nding the best position for the antenna. Keep the
antenna in your hand and try to reach the highest possible position. Now slowly turn the
antenna around its axis (in the horizontal eld), at the same time monitor the signal bars
in the menu, once the signal indicator shows the maximum signal, x the antenna on that
position.
5. It is important to place the antenna in such way that an acceptable signal level is assured.
You can optimise the signal strength by moving the antenna to dierent locations in your
room, for example place it near a window, or place it on a high placed book-shelf. The best
position can be found by trying dierent locations.
NOTE: It is recommended NOT to place the antenna near to:
 Devices that are strong source of radiation or interference such as DECT and GSM
telephones, transmitters, microwaves, etc.
 Devices with high power consumption such as electrical heater, air conditioner, hairdryers, etc.

B: To power the antenna with extra power adaptor
1. Use this installation if your Digital Terrestrial Receiver does not support an active antenna.
2. Connect the supplied power adaptor to the “DC IN” connector on the back of the antenna.
3. Proceed with positioning the antenna as described above in section A (points 3, 4, 5).
NOTE: The antenna will not function properly if the built-in amplier is not powered.
Therefore it is required to supply the antenna with power via the coaxial cable or via
an external adapter.
Extension of the coaxial cable:
In some cases you may need to extend the standard supplied coaxial cable, we advise you to only do so
if you cannot get optimal signal strength within the reach of the standard cable. If you are to extend the
coaxial cable, then please note following comments:
 Use a good quality coaxial cable, 75 Ohm type only with proper shielding
 Use well shielded connectors, your dealer can advise you on this.
 Make sure that both inner cable and shielding are properly connected to the connectors to
assure active antenna power supply and to avoid short circuit in the cable.
If you extend the cable, please keep the cable as short as strictly needed. Extending the cable or using bad
quality cable will reduce the performance of your antenna.
