Probably, many of us do not do a day without watching television. News, any interesting programs and programs - all this has become commonplace for us. And of course, all this cannot be broadcast without an antenna. You can buy such a device in any store at an affordable price, but if you have a few extra cans, a couple of meters of a television cable and a soldering iron, you can do it yourself. Yes, it is from such tools that we will today learn how to make such an apparatus as the UHF antenna.
Instruments
To begin with, we need to prepare all the associated devices and mechanisms. In addition to two cans, a soldering iron and a cable, we will also need tape, plugs and a wooden trempel. Together, all of these mechanisms will produce a completely normal, and most importantly, a functioning antenna.
Modifying the cable
In the question of how to do the DMV antenna with your own hands, you must first pay attention to the cable. We should modify it a bit. To do this, make a small incision on its soft shell. Under it you will see something like a silver foil. The cable is located in it. So, its upper layer should be cut off by about 10 centimeters from the edge, and then twist the foil and cut its center by 1 centimeter. In this case, the second end of the device must be connected to the plug, which then must be connected directly to the TV.
How to make an antenna with your own hands? Mount banks
Now we take up our "containers". It is important to ensure that the volume of cans is at least 700 and a maximum of 1000 milliliters. When you cut their upper part, do not throw away or tear off the keys, as we may still need them in our work.
In order for the UHF antenna, made with its own hands, to function normally, take the following steps with special care and attention. Now we need to connect all the prepared devices (namely banks and a cable with a plug) into one. The cord should be connected to the tin container so that the foil rests directly on the metal surface of the can. Next, you need to apply tape or, best of all, electrical tape for the reliability of the fasteners. Of course, we cannot guarantee you a perfect connection, however, there are simply no other methods, because the use of a welding machine will simply burn through the thin wall of our tank. The only thing you can try is to make a connection using a soldering iron. Further, in order for the DMV antenna, made by oneself, to have good reception quality, it is necessary to fasten the cable elements to the keys.
Point of reception
Now we attach the jar to the trempel (again using electrical tape) and connect the cable using the plug to the TV. It is important to find the best point of reception before this. If it is a private house, the DMV antenna is installed on the roof with its own hands, if it is an apartment, then on the balcony. In these places, as practice shows, the best points of signal reception.
