Everyone wants to watch their TV ingood quality, but not in all regions it is possible. Somewhere a bad signal, somewhere in general it is missing. Therefore, in this article we will look at how to make an antenna for a TV set with our own hands.
There are many options, but you have to choose one that will fully satisfy your requirements.
For example, from two tin cans of half-litercan turn out worthy replacement store antenna. But here there is a minus. Such an antenna will only work in the DMV range. To achieve more channels, two liter cans are required.
Assembly
To one bank it is necessary to solder the central vein -signal, to the other - shielded braid. Then attach them with tape to the bottom of the trempel. On the reverse side, the antenna plug is removed. To get a decent picture quality, you need to adjust the distance between the banks. So, how to make a self-made antenna, the simplest, you understand.
Antenna with loopvibrator is much more difficult, but the quality of signal reception is higher. Here, a calculation is required. Since such an antenna is broadband, it must receive several channels, and depending on the numbering of programs, the size of it must be different.
Now we need to figure out how to make the antenna for the TV with the least losses and costs.
The main pipe, as well as all the restparts, should be made of brass, copper or aluminum. Their surface can not be rough. The steel antenna will turn out to be very heavy and the signal reception at it will leave not qualitative. In addition, it will rust. It is supposed to be mounted on the street.
The length of the main tube should be two meters. On it, with the help of screws with a diameter of 5 mm, are attached tubes of smaller diameter "directors". The distance between them should be 30 cm. A drill and a drill 5-6 mm in diameter are required for assembly. The length of each subsequent tube should be 10 cm shorter. That is, the very first "director" located at the bottom will be equal to 60 cm, the next 50 cm, etc.
Opposite the biggest director, a reflector is attached to the base of the tube. It is a construction of three "directors", connected in parallel. Then a vibrator is mounted on the pipe.
For many, it remains a mystery how to make an antennafor a TV so that it looks aesthetically pleasing, it was not bulky and at the same time accepted all existing channels. As you understand, there is a way out - this is a director's antenna with a loop oscillator.
We continue the assembly. After the antenna has already been assembled, solder the loop. Take a piece of antenna wire 60 cm long and 75 ohms resistance. Next, we clean the ends so that the braid is joined together and attached to the main tube. And the central wires are to the vibrator. All joints must be sealed well to avoid moisture ingress. The vibrator is a loop made of the same material as the antenna itself. The distance between the ends of the vibrator should be 10 cm, and lead them to the central wires. Then connect the antenna wire with a plug of the correct length.
We have many settlements in our country, where civilization has not yet reached, and such advice as how to make a home antenna, is still relevant.
Typically a director antenna with a loop oscillatoris set as high as possible. It is better to take a wooden bar measuring 50 mm by 50 mm and a length of 6 meters, fix the antenna on it, distribute the wire along the entire length and install the structure on the roof of the house.
Thus, from this article you learned how tomake an antenna for the TV, without recourse to specialists, without spending money to purchase it and an amplifier in the store, if you live in a remote region. Experiment.
