Hello! In this video I will show the most that neither is.
We will need:
- A piece of antenna cable, about 25-30 cm long
- Antenna connectors, the so-called F - connector and male - female connector.
- Knife, wire cutters and necessarily a ruler
Now we need to calculate the length of the antenna itself and then proceed to its manufacture. To do this, go to the digital television website, select a country, in my case it is Ukraine and look for the nearest station for your city.
We look that the minimum frequency of our tower is 490 MHz (23 channels), and the maximum 586 MHz (35 channels)
Now we calculate the length of the antenna. I will not go into complex technical formulas and terms, we do not really need them. But to calculate the antenna, you need to divide 7500 into our frequencies.
That is: 7500/490 = 15.31 cm (23 channel),
7500/586 = 12.80 cm (35 channel)
Plus two of these lengths and divide by 2: (15.31 + 12.80) / 2 = 14.1 cm
The length of our antenna is 14.1 cm
Manufacture
1) We take a piece of antenna wire and for a start we attach the F-connector at the end. Just strip the cable and wrap the connector so that the central wire is in the middle and the screen is in the mount.
2) We postpone a couple of centimeters from our connector (this will be a kind of indentation), then measure out 14.1 cm and cut off the unnecessary cable.
3) Now with these 14.1 cm, we need to remove the plastic sheath and remove the “screen” (foil and small wiring). You do not need to touch further, we leave the cable in the insulator.
4) We measure exactly 14.1 cm and cut off the excess
5) Bend our antenna at 90 degrees for convenience and insert it into the console.
P.S. The cable length can be made several meters. If the antenna does not catch the signal well, it should be placed closer to the window.
