This is a specially designed antenna far from both analog and digital terrestrial TV broadcasting reception. Lt can receive all the TV signals of your area in the VHF and UHF band, as well as the FM radio signal. It is the best solution for home reception and digital portable TV reception. This antenna is an active antenna powered through AC power. It is very practical to install and very easy to use.

Technical Data:

  • Frequency range: VHF: 87.5-230MHz: UHF:470-790MHz
  • Receiving Range: FM/VHF/UHF
  • Gain: 30dB(max)
  • Output Level: 100dBpV Max
  • Out Impedance: 75
  • Noise Figure: 3 dB
  • Power Supply: Via AC/DC adapter (DC12V/200mA)

Product Features:

  • Variable gain control
  • Power On/Off LED indicators
  • SMD circuit technology design
  • Built-in high gain and low noise amplifier
  • Adjustable loop aerial for the best UHF reception
  • Adjustable Telescopic antennas for optimum VHF and FM radio reception
  • Stylish and compact size design with highly innovative technique process
  • Adjustable gain to fine-tune the best reception for both digital and analog TV signals.
  • Specially designed for HDTV of various digital terrestrial signals (DVB-T, DMB-T/H, ATSC)and DAB/FM radios.


Note: For the best reception, please check the following conditions

  1. Keep the antenna away from the sources of interference: keep the antenna away from those big power consumption devices, such as air conditioner, elevator, hairdryer, and microwave oven …
  2. Place the antenna near windows when using the antenna in indoor
  3. install the antenna as high as possible: in digital terrestrial reception, if there are some interceptions between antenna and transmission tower, it will cause the signal to toss temporary. So if the antenna is installed as possible, those interceptions will be reduced.


  • Connect the adapter to the antenna.
  • Connect the cable to a set-top box or TV

After checking that all the connections have been done properly, turn clockwise the ON/OFF knob (5) to switch the antenna on: led (3) lights up showing that the amplifier of the indoor antenna is working. Now, turn your television set on and select a TV program, then adjust the rod antennas (6), the dipole antenna (5), and the amplifier gain (4) according to what is described in the next paragraphs.


VHF SIGNALS – I-III BAND (channels 1-12)

This antenna receives VHF signals (both analog and digital) through the rod antennas (6). Far best reception, adjust rod antennas as follows:

  • for I Band: extend completely the rod antennas;
  • far III Band: shorten the rod antennas to about 16 inches (the extension depends on the channel you want to receive);
  • then, move the rod antennas until you get the best signal reception.

UHF SIGNALS – IV-V BAND (channels 21-69)

This antenna receives UHF signals through dipole antenna (5):

  • tilt the dipole up and down;
  • turn the dipole sideways until you get the best signal reception.


In order to adjust the amplifier gain turn the 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 a TV or terrestrial set-top box, please make reference to the following 2 different connecting ways to install your antenna.
