Digital television today continues to spread every day. Providers offer their services in this area by selling expensive devices. However, you can "catch" on-air digital television using a makeshift antenna.
We offer you to watch a video on the manufacture of the antenna:
So we need:
- decimeter antenna;
- calculator;
- antenna cable;
- connector for cable;
- ruler
First of all, it should be noted that to receive digital TV channels you need a TV with support for the DVB-T2 format, otherwise the antenna will not fulfill its purpose. It should also be clarified that providers often advertise the so-called digital antennas, which are supposedly created specifically for receiving digital television channels. This is not so, since it is possible to catch such channels even with a wire. With the materials and the introductory part sorted out, you can get to work.
Next, we find our district or city on the site to find out the center for consulting support or, more simply, the broadcast center. The next thing we call the support center and find out which channel is broadcasting digital television. The author, for example, broadcasts on channel 27. At the end of this stage, we find out the frequency of the channel.
Now, with the help of a calculator and a special formula, we have to find out the necessary length of our antenna. The formula is extremely simple: 7500 must be divided by the number of channel frequencies. The author has a channel frequency of exactly 522,000 kHz, that is, you need to divide 7500 by 522. It turns out 14.3 approximately. We round the result obtained after dividing and get the antenna length in centimeters.
Next, take a regular antenna cable, strip it on one side and insert the connector.
The next step is to take the ruler and measure the result obtained by dividing, without forgetting to leave 2 centimeters in the base. That is, if the author needs a cable 14 centimeters long, he measures 2 + 14 cm.
Cut off the end. After that, we make an incision on the base line and clean it to the convoy. We remove the cable protection, because we do not need it. Also cut the foil.
After that, we bend the cable at the base line at a right angle. The antenna is ready. It remains to install it outside so that it looks towards the transmitting antenna. It is worth noting that if the distance from the transmitting antenna is more than 15 km, then you will have to use an antenna amplifier.
To watch digital television on a TV, go to the settings, specify the channel, frequency.
