How to Make an Indoor TV Antenna – Once upon a time in my room there was a TV that was never used to watch TV because the outdoor antenna was installed on the roof, the cable was not connected to the room.
So it’s been a year since TV has only been used to watch movies from a laptop via an HDMI cable. This morning I decided to buy an indoor antenna, and before hunting as usual I made it a habit to ask Google which antenna is the best + cheap.
After a few minutes of gugling it turned out that what came out was more “how to make a simple TV antenna”. After looking around, reading and weighing it, it looks like it’s easy to make an antenna too.
As a result, I did not hunt the antennae, instead I went hunting for building materials to the material shop. Hahahahhaha. Let’s just take a look at how this masterpiece was made
How to Make an Indoor TV Antenna
A. Tools and Materials
How to Make an Indoor TV Antenna:
- Nisplang zinc (seng gutter) 0.5 x 0.5 meter
- Coaxial cable impedance 75 Ohm, 5 meters (adjust)
- Coaxial cable jack to TV
- Lath wood or used bottles or the like, which is important
- Length 11 cm
- 3mm bolt nut, 2 seeds
- 3 cm wood screws, 2 seeds
- Cutter and scissors
- Soldering iron and tin
B. Tools and Materials.
All of the above materials can be found at the nearest material / building shop, this is the picture if you are confused.
- Nisplang Zinc: 35000 (1 × 1 meter)
- Coaxial Cable: 35000 (5 meters)
- Coaxial Jack: 2500 (the usual), 5000 (the aluminum shield is good)
- Nut Bolt Screw: 2000 (4 seeds)
- Kayu Reng: take from the roof of the house next door
- Bottles: used Vixal bottles in the bathroom.
- Solder & Timah: the remaining osjur is still there.
- I actually spent 100 thousand in total, because I bought a lot of screw nuts, the jack bought 2.
C. The Workshop Begins.
Cut the zinc so that it looks like the image below
The butterfly-shaped zinc is driven, the one on the right is a reflector. Then cut the used bottle so that it is used in the form of a tube with a length of 11 cm. The diameter is free.
If you use batten wood, you can also cut it to a length of 11 cm. Then attach it using a screw or bolt so that it looks like the one below.
Then stick driven + bottle above to the reflector. I do how to help the reflector in 4 different places, according to the place where the bottle is built too. Then connect it using a cable tie.
Continue to add more screws 1 each on the top of the driven, this screw functions as a place to attach the conductor and ground of the coaxial cable.
The conductor to the driven fault and ground (the fiber portion) to the other driven. You are free to drive whichever you want, but don’t mix it.
Then solder the conductor hook to the screw, then tighten the screw.
So the drive is very united with the conductor and the ground. So it looks like the picture below. Oh, don’t forget to connect the other end of the cable to the coaxial jack.
Taraaaaaaaa! so please. The antenna is ready to be tested, and the results are STUNNING. Just put the antenna on the floor, the picture is still pretty good. Better than the indoor antenna my brother bought back then for 75000.
Then I tried this ‘cupu’ antenna placed on top of the cupboard. Wow, it’s great. Finally, the antenna is hung above the door so that the cable can be tidied up.
All national TV is clean without ants (except Tr * ns brothers, antenna direction is different). Local TV has a little ant. This is the appearance if you don’t believe it
Great, right? and this DOES NOT USE THE BOOSTER.
Now let’s compare the prices
How to Make an Indoor TV Antenna
Antenna above the price is above 75 thousand, the cable is only 2 meters if I’m not mistaken
Whereas the antenna I just made:
zinc = 1/4 square meter => 1/4 * 35000 = 9000 rounded
5 meter coaxial cable + jack = 37500
screws, nuts, bolts = 2000
Total only 48 500! even if the cable is 2 meters, only about 35 thousand. Indeed yes, hard effort will not betray, even this is not a very hard effort. I made this 2 hours effective too.
Even though I am an electrical engineer, to be honest I don’t know where the driven and reflector size figures come from, maybe I should take a telecommunications (antenna) course, so I can see how this cupu antenna is better.
