• Place the antenna in a position with good reception, for example near a window or in the direction
of the television station, away from metal objects, electrical appliances and reinforced concrete
walls which can attenuate the signal and limit its operation
• Connect the Meliconi antenna cable [A] to the antenna input socket on the TV (or digital terrestrial
decoder).
• Turn knob [D] counterclockwise and adjust for maximum amplification.
• Connect the end [F] of the power cable [B] to the antenna [C]; insert the other end of the power
cable [G] into a free USB socket on the TV (or decoder). In this way the TV (or decoder) will
automatically supply power to the antenna only when it is switched on.
• Turn on the device (TV / DECODER) and select the desired channel. Check that the LED [H] on the
antenna turns on. When the TV (or decoder) is turned off, the antenna (and LED) should turn off.
If your TV / decoder does not have a free USB socket, you can power the antenna in the following
ways.
B1 POWER SUPPLY FROM DECODER
• If the antenna is connected to a suitably equipped digital terrestrial decoder, the decoder can
power the antenna via the antenna cable [A] (refer to the decoder's user manual to enable the 5 Volt/
Antenna connection).
Check that the LED [H] on the antenna turns on when decoder is on.
In this configuration, when the decoder is turned off, the antenna (and LED) will automatically turn off.
B2 EXTERNAL POWER SUPPLY
• Use a standard 5 VDC/1 A USB power supply (not included) that complies with current safety
regulations.
Meliconi S.p.A. denies any and all liability resulting from use of external power supplies.
C
If the image quality is unsatisfactory or no signal is received, proceed as follows:
• Check that the antenna is on: LED [H] on.
• Turn the antenna until you get the best reception.
• Adjust the gain with the amplification adjustment knob [D]; the maximum gain setting does not
always give the best image quality. Try reducing it a little.
• Look at the antennas on the roofs of neighbouring buildings and turn your antenna in the same
direction as them.
