Simple antenna for digital television

The antenna is designed to receive digital television channels in the DVB-T2 range. It has a very simple design and repeatability. It can be used as a home or outdoor antenna. Good for long-distance use.

Will need


Materials:
  • Single-core copper wire 3 mm in diameter.
  • Cable television with a plug.
  • Plastic round balls for the base.

Tool:
  • Soldering iron with solder and flux.
  • Hot glue gun.
  • Nippers.
  • Pliers.
  • Roulette or ruler.

Production of an antenna for digital television DVB-T2


A drawing of the antenna looks like this:

This is one of the most popular types - double biquadrat, it is also called the Harchenko antenna. It is tuned to mid-range DVB-T2.
For its manufacture, you can use a wire and a larger diameter than 3 mm.
We take a tape measure, measure according to the drawing the sides for bending.

With pliers we make bends forming a square.

We make two such squares for both arms of the antenna. At the ends, making loops is not necessary, but it is easier to solder the squares with each other.
Now wet the junction with the flux.

Solder solder both squares in one.

Solder the cable.

Put on the plastic round and pour hot glue on the spot, while gluing the antenna to the plastic.

The antenna is ready. It can be hung from this plastic round.

The antenna perfectly catches at home and on the street. It is suitable for long-distance reception in the country. As you can see, the design is unusually simple, which gives it significant advantages.
Now we direct it to the transmission station and start the automatic search.
You can also refine the design with a reflector, cutting it out of a piece of tin.
I also want to focus your attention on the endurance of dimensions during manufacture, since a slight deviation from the set ones can significantly reduce the quality of digital channels reception.
If you use the antenna on the street, but it will not be superfluous to paint it, protecting it from weather conditions. Although, it seems to me, nothing will happen to her anyway.

    Yes. Such an antenna works well. I would like to clarify - perhaps a television cable needs to be laid on two sides of one of the square, this will play the role of a matching transformer.

    it is also called the Kharchenko antenna

    Yes, this is Kharchenko’s antenna.
    But sorry in a complete perverted view.
    In this design, it’s just a quarter wave dipole, which is absolutely not aligned with the drop cable.

    To become an Kharchenko antenna, it must be rotated 90 degrees and a drop cable must be laid on two sides of one of the square (bottom) there is the zero point of the antenna (at this point you can make grounding if the antenna is external).
    Zero point disconnects the drop cable from spurious signal reception.

    This is not an antenna, but it will catch something like any wire.

    A beautiful antenna was obtained from a section of a metal-plastic water pipe with a diameter of 20 mm and a length of 66 cm. In the middle of the pipe, a strip of aluminum foil was removed around the circumference (5 mm ring). It turned out like two pipes connected by an internal plastic (half-wave vibrator), to them, with the self-tapping screws, the terminals of the television cable are attached (without any coordination). It perfectly catches TWO packages (20 channels) of digital television.

    I'm not special, but having calculated the sides of the square according to the frequency of my region of 482 MHz, what this antenna didn’t catch, why
