Being far beyond the city, where you rarely meet a house with a satellite plate, and there is no possibility to connect cable TV, sometimes you think about, but how to make an antenna for the TV with your own hands.
Indeed, because with an old antenna can happen anything. The cable was damaged, the signal disappeared, the wire was moved and you were left without television. The situation is unpleasant, but, as it turns out, quite corrected. Such a problem is solved if you succeed in building a room antenna from undergraded means and, perhaps, without even resorting to the assistance of the soldering iron.
The easiest way to make tv antenna
Living in an apartment building, we are not insured against problems with the possible lack of TV-broadcast. But it is possible to solve the problem quickly and quite efficiently. For this, we need copper wire and knife. We clean the knife of both ends of the wire and one of them, tie to the heating battery, and the other insert your TV into the socket.
Include it and check the signal. The central heating battery stretches to the roof, thereby increasing the signal, so we cannot guarantee a hundred channels, but 5-7, such an antenna will catch and provide a rather high-quality display.
TV antenna from aluminum cans
The unfair person is unlikely to guess that the room antenna can be made of ordinary beer, or cans from Coca-Cola. Moreover, this method has been known for a long time. For this we need the following items:
1. Two aluminum banks.
2. Brass, copper wire or old television cable.
3. Triangular hanger for clothes.
4. Soldering iron (for the strength of the design and improve the signal, but can be without it).
5. Knife.
6. Healent, Scotch.
Making antenna manufacturing process
We rinse banks and carefully by their envy. Then, fix on the edges of the hangers so that they lay down to the underside. Consolidation of cans produce, best, with a scotch or tape, but other remedies can also be used. It is necessary that the banks keep well.
Then, we clean the ends of the wire or cable on both sides and produce their ends through the ears, with which banks are opening. We press these ears to the lid of the can and insert the other end of the cable into the connector.
Note!
For the strength of the design, the wire can be soldered to the bank and insulate these places.
To increase the number of channels, you need to use larger diameter banks.
TV Antenna Decimeter and Meter Range
If you have small skills to work with a soldering iron, then you can easily assemble the antenna for the TV with your own hands of decimeter and meter ranges. The design does not require engineering skills and for creation we will need: 1. Copper wire with a length of 80 cm and a diameter of up to 3 mm. 2. Bilateral fiberglass. 3. Coaxial cable up to 2 meters long and resistance in 75 ohms. 4. Plug.
The procedure for making a decimeter antenna
To begin with, you need to find a wire of copper with a diameter of 2-3 mm. More others suitable for this, a single-core cable used when installing wiring. If you find a stranded wire, then it is necessary to separate one living, without damaging isolation. In the extreme case, you can use the wire from aluminum. If there is no insulation on the wiring, then for aesthetics, it can be brought into the tube, for example, from chlorvinyl. Then, make a circle from the wire, having a diameter of 22 cm. For the convenience of making such a circle, you can use any capacity of similar diameter.
Assembling board
To continue the assembly of such an antenna for television, you will have to independently make a fee. There is nothing difficult in this. We take a piece of textolite in size of 2.5 * 3.5 cm and a thickness of 1.5 mm, and placing the track from the copper wire on its surface, as indicated in the diagram.
Place assembly scheme
The wire diameter must be in the range of 0.4 mm. It can be fixed on a fee with glue. To reduce the effects of the outside and giving our design of a beautiful view, hide our fee in a plastic box or metal, in advance drilled holes for the ring and cable. After these preparatory work, we start collecting the design.
Build the design of tv antenna
Renting the annular ends of the solder and bring them to our box with a board. Then we join them at right angles, we bring to the board and make a seal. After that, turn the fee to the bottom of the box and begin the preparation of the cable. For this, one end of the cable is set the plug, and the second, disconnect and solder to the board on the reverse side. One of the ends, the central custody, fix the rings to the right end, and the second, we solder to the board of our product. After these manipulations, the design is ready. Insert the plug into the television socket and hold the channels.
TV antenna for digital television do it yourself
In the hands of a soldering iron and a screwdriver in the hands, at home can be done at home the antenna for digital television, which will be high-quality many Chinese analogues who flood our market and most importantly, almost free. To do this, we need the following items: 1. The board of 7 cm wide and a length of 55 cm. 2. Wire of copper, a length of 39 cm and the diameter of the central vein 4 mm. 3. Self-tapping screws in the amount of 10 pcs. 4. Pencil, line, knife. 5. Plug.
To begin with, we take the skid of the desired size and make markup according to the scheme:
The procedure for performing the design
Dimensions are indicated in inches. To translate into centimeters, multiply by 2.5 and round up to the tenths. For example, 2 and 5/8 ", when multiplying, we get 6.56, round up to 6.6 cm. Then we cut our wire on 8 parts and we get slices of 37.5 cm. On each piece we make cuts for 2 cm long compounds, and we clean them. After that, we cut two more wires by 22 cm and we clean in places where connections will be made. The wires that we pre-cut 37.5 cm, bending the letter V so that the distance between the edges was 7.5 cm.
Finishing stage assembly antenna
Now that we have a real television antenna for digital television, you need to complete the assembly correctly. To do this, we need to buy a plug with a coil inside and start the process of connecting the coil with a cable. Connecting the cable to the coil occurs through the lower contacts. After that, we complete the antenna assembly, screwing two wires, with a length of 22 cm, to central self-drawing. On the other hand, these wires are attached to the plug with the coil, which, in turn, must first be attached to the reverse side of the plank. All, the coil is ready to use.
Frame wave canal
For the manufacture of such antenna, take copper wire and will bend from it the frame. The side of the frame should be about 10 cm. In place of the connection of the ends, we associate them by the method of "pigtail". After that, after 2 cm, begin to twist the same frame, connecting the ends in a similar way.
Note! The number of such squares should be equal to four and all of them are on the same wire.
The resulting simple design will allow you to replace the spoiled antenna in five minutes and get enough high-quality picture on the screen of your TV. All listed ways of assembling antennas with their own hands will allow not only briefly taking advantage of inconvenience, but also to use for a long time without spending money to buy new devices.
