How to make an antenna for a TV - 4 simple ideas

Idea # 1 - Beer banks in use!

This version of the home-made television antenna is the simplest and fastest in manufacturing. The maximum number of channels that will be provided at your disposal is 7, but this figure may vary slightly depending on the region.

To make an antenna for a TV from beer cans, you will need the following materials:

• 2 small self-tapping screws, also called "bedbugs";
• 2 prepared beer cans( empty, washed and dried);
• from 3 to 5 meters of a television cable( you can take it from an out-of-order device);
• soldering iron and tin( for better fixation of contacts), availability is not mandatory;
• screwdriver;
• wooden thruster;
• tape or tape.

All the materials found in the house will not be a problem, so preparing them immediately goes to the point.
In order to make a self-made antenna from the cans, you need to perform the following steps:

1. Prepare the cable. First, at a distance of 10 cm from the edge, an incision must be made and a part of the upper layer of insulation removed. Having opened access to the screen, we minimize it in one turn. After that, we cut the middle insulation layer, revealing the thin copper core of the cable. As for the second end of the conductor, there should be a normal plug.
2. Preparing the banks. With capacities that act as a signal receiver, no complications will arise either. First you need to choose the optimal size of beer cans. It is better to use liter, but if they are not available, they will do well with the task of capacity of 0.5 and 0.75 liters.
3. Bringing in contacts. At this stage, the twisted cable screen is fixed to one bank, and the copper wire itself to the other. Fixation is carried out by bedbugs with the help of a screwdriver. In order to make the picture quality on the TV screen higher( the quality of signal transmission), it is recommended to fix the wire not only with bedbugs, but also with a soldering iron( grab a little).The result should look like this:
4. Assembling a self-made antenna for the TV.The signal receiver is ready, now we make the supporting structure, which we have tremble. With the help of an insulating tape we fix the containers to the trempel( as shown in the photo).We draw your attention to the fact that banks should be strictly on the same straight line, otherwise the homemade work will not work as we would like.
5. Adjust the antenna for the TV.Now you need to experiment with the optimal distance between the banks, as well as the place of suspension of the device, so that self-catching would catch many channels. Turn on the TV and determine exactly how the receivers should be located and where the most suitable place to work. This completes the technology of creation.
   
   

As you can see, the whole process is quite simple and does not represent anything complicated. The optimum distance is 75 mm between the ends of the cans, and the best place of installation is near the window. In individual cases, the distance between the banks can be made more or less.

Idea # 2 - Using

wire Another no less good option that is advisable to use in the village is a self-made antenna made of copper wire with an amplifier.

All you need to make is:

• amplifier( coming from an old device);
• two pieces of wire of 180 cm;
• piece of metal( or wood) plate 15 * 15 cm;
• electric drill with a set of drills( or welding machine);
• small bolts;
• hammer;
• iron pipe;
• TV cable of suitable length.

So, to make the antenna for the TV set from copper wire, you need to perform the following steps:

1. Prepare the trap: bend the wire with a diamond to all sides were strictly 45 cm( the inventor of the homemade claims that this is the optimal size of the device).
2. Fix the wire to the prepared plate: flatten the veins in the attachment points, drill the holes and tighten the bolts. If there is a welding machine, it will go faster - you just need to grab the signal traps to the plate. Immediately you need to connect the amplifier( as shown in the photo).
3. Connect the cable. Everything is simple, becausejust insert the plug into the connector.
4. We create a mast, for which we use a metal pipe of suitable height. We dig it in and the homemade antenna for the TV is ready, you can start tuning the channels.

Please note - in the photo examples and the amplifier, and the reflector, and the wire are covered with paint. Staining protects the structure from corrosion and other unfavorable factors, significantly prolonging the life of the homemade antenna for the TV.

Idea # 3 - Home HDTV device

If the first 2 options worked at a frequency of no more than 270 MHz, then the following manufacturing method will allow you to enjoy a better picture, becausethe signal range can reach up to 490 MHz. The only detail that is unlikely to be found among domestic trifles is the matching transformer from 300 to 75 Ohm. It will need to be purchased in advance if you decide to make an antenna for the TV yourself as an experiment and improve your skills. Although there is an instruction for manufacturing a self-made transformer, you can find and use it.

From materials You will need:

1. Adhesive tape
2. Cardboard
3. Stationery knife
4. Foil
5. Stapler
6. Scissors
7. Marker
8. Roulette
9. Glue

Having prepared all this school kit, get down to business!

Now, according to the scheme, we cut out all the spare parts, including the necessary pieces of foil:

Next, we glue the cardboard butterfly with foil and paint the back part with a marker.

After this, you need to make a reflector measuring 35 * 32.5 cm( height and width).One side is sealed with foil.

In the middle, we cut out two identical rectangles, which are necessary in order to completely assemble the signal trap of the homemade antenna for the TV.The rectangle should be 3.5 cm long, its purpose - to maintain the distance between the reflector and the auxiliary parts.

We paste the parts on a rectangle, and when the cardboard self-mold is frozen, we drill the holes for the television cable.

Connect the transformer and plug the cable into the plug. A more powerful antenna for the TV is ready for use! Immediately it should be noted that this version of the homemade fits only for room use, tk.paper quickly deteriorate outside.

Another version of a powerful device made at home:

tools Idea # 4 - Apartment version of the

There is another way to make a powerful antenna for a TV from improvised means, which is suitable for both street and apartment use.

For the manufacture of the device you will need the following materials and tools:

• 4-meter wire made of copper, section 4 mm.kv;
• board of arbitrary thickness, 55 cm long and 7 cm wide;
• wood screws;
• ruler or roulette;
• simple pencil;
• screwdriver;
• soldering iron;
• plug.

So, first, according to the drawing, we drill the holes in the board:

Then we transfer the drawing data to the board and drill into the corresponding mounting points.

The copper wire must then be cut into 8 pieces of 37.5 cm.

In the middle of each of the 37.5-centimeter lengths, it is necessary to remove the insulation( as shown in the picture).

Cut another 2 copper pieces of wire length of 22 cm and conditionally divide them into 3 equal parts, while at the inflection points, again, remove the insulation.

Mend prepared wire in bare places. We draw your attention to the fact that in those segments that are bent in half, the distance between the ends should be made 7.5 cm( the optimum value for receiving the signal of a home-made television antenna).

Next, we attach the plug to the finished self-made plug, and we already connect the television cable to it.

This completes the manufacturing process. Choose the appropriate place and install the device.

Here we have provided the most simple instructions. We hope that now you know how to make a home TV antenna yourself! We draw your attention to the fact that today on the Internet you can find many other options in which inventors do without cans and wires. Of the remaining improvised tools, copper tubes, aluminum disks and electrodes are often used. The advantage of the options listed by us is that you can quickly make such antennas for your TV without spending it all evening.
