Setting and connection
• Connect the AC 230V cable (1) to the 230V AC wall socket.
• Connect the TO TV cable (2) to the antenna-input socket of your TV or terrestrial digital set-top-box.
• Connect the AC 230V cable (1) to the 230V AC wall socket.
• Connect the TO TV cable (2) to the antenna-input socket of your TV or terrestrial digital set-top-box.
After checking that all the connections have been done properly, turn clockwise the on/off knop (4) to
switch the antenna on. LED (3) lights up showing that the amplifier of indoor antenna is working. Now,
turn on your television set on and select a TV programme. then adjust the rod antennas (6), the dipole
antenna (5) and the amplifier gain (4) according to what is described in next paragraphs.

Signal reception
VHF SIGNALS - I-III BAND (channels 1-12)
This antenna receives VHF signals (both analog and digital) through the rod antennas (6).
For best reception, adjust rod antennas as follow:
• For BAND I: extend completely the rod antennas
• For BAND III: shorten the rod antennas to about 16 inches (the extension de pends on the channel

• For BAND III: shorten the rod antennas to about 16 inches (the extension de pends on the channel
you want to receiver)
• then, move the rod antennas until you get the best signal reception.
UHF SIGNALS - IV-5 BAND (channels 21-69)
This antenna receives UHF signals through dipole antenna (5).
For best reception, adjust rod antennas as follow:
• tilt the dipole up and down
• turn the diplo sideways until you get the best signal reception
This antenna receives UHF signals through dipole antenna (5).
For best reception, adjust rod antennas as follow:
• tilt the dipole up and down
• turn the diplo sideways until you get the best signal reception
Gain adjusting
In order to adjust the amplifier gain turn on/off knob (4) until to get the best signal reception:
• to increase gain, turn the knob clockwise
• to reduce gain, turn the knob anticlockwise
In order to adjust the amplifier gain turn on/off knob (4) until to get the best signal reception:
• to increase gain, turn the knob clockwise
• to reduce gain, turn the knob anticlockwise
Note: This antenna can be used directly connected to TV or terrestrial set-top-box, please take
reference of following 2 different connecting ways to install your antenna.
