1.0 Introduction
Thank you for purchasing the Strong SRT ANT 15 DVB-T Antenna. This antenna has been specially
designed to receive digital terrestrial signals. It can be connected to any Digital Terrestrial Receiver
(DVB-T), and is specially designed for Outdoor use. The antenna housing is UV protected and
weather-proof sealed. With the multi-functional mounting materials supplied you can install the
antenna on a wall, on your balcony or on a pole outside the house.
This DVB-T Antenna is an “Active type” antenna, it has a built-in low noise amplifier that amplifies the
received signal for better performance. The antenna therefore needs 5 V power supplied by your
terrestrial receiver, or by an AC adaptor (supplied with the antenna).
We recommend that you carefully read this user manual before you install the antenna. This will help
you to get the best performance out of your antenna.

5.0 Installation of the antenna:
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. Select the Menu
on your receiver that shows you the signal level indicators. (Normally you can find the signal meter in
the Channel Scan field of the menu). Refer to the User Manual of your Digital Terrestrial Receiver.
3. Now optimise the signal strength by finding the best position for the antenna. Keeping the antenna
in your hand, try to reach the highest or best possible position. Slowly move the antenna to different
positions around the house, at the same time monitor the signal bars in the menu, once the signal
indicator shows the maximum signal, fix the antenna on that position.
Note: It is recommended NOT to place the antenna near to:
n Devices that are strong source of radiation or interference such as DECT and GSM telephones,
Transmitters, Microwaves, etc.
n Devices with high power consumption such as Electrical Heater, Air conditioner, Hairdryers, etc.
Once the best position for the antenna has been found it can be mounted and fixed in that place.
You can fix the antenna on the wall, on the balcony or on a metal pole.
