Installation instruction:

Before set up the connection, please ensure the mains for the antenna and TV set are unplugged or switched off.

1. Insert the belling-lee plug (RF plug) of the device into the signal input on the back of the TV set or set-top box.

2. Plug both antenna and TV set to the mains supply and switches both on.

3. The control knob in the middle of the antenna serves as gain control and can also use to switch the antenna off

by turn it to minimum gain (anti-clockwise). Please adjust the gain to midway at this stage.

4. To get best reception for UHF signals, face the circular dipole towards the preferred transmission tower and

adjust tilt until best picture quality is shown on TV.

5. For VHF reception fully extent the telescopic antenna and swirl around until best picture quality is shown on TV.

6. Fine adjust the gain control until best quality is received.

The FM signal received by the antenna will be amplified through built in amplifier and send to the TV set through
connected coaxial cable.

Set up tips:
This antenna is fitted with built in 4G filter to eliminate 4G interference, however other interference may still exist.
Therefore for best picture and sound quality we are advice not to place the antenna near source of interference such as
mains cable, hair dryer, microwave etc (high power consuming appliances).
The antenna position should be as high as possible for best reception as the more the obstacles occurs between the
transmission tower and antenna the more the interference will be. Also please note the best reception position may vary
for different channels.
Once set up is finished avoid moving the position of the antenna as picture/sound quality may be distorted when antenna
is shifted.
If reception remains poor, this may be caused by the nearby strong electromagnetic field. Please try relocating the device
away from appliances and walls (mains cable inside).
