Why is the DTH antenna installed diagonally… If you put it straight, will the channels get more clear?
The system works in the DTH antenna as well as in the large umbrella dish antenna. In DTH, the antenna captures the signals and converts them into pictures in our TV. This will not happen if the antenna is not mounted diagonally.

Simple Antenna to DTH Journey: There was a time when there was only Doordarshan channel. Ramayana-Mahabharata and Rangoli-Chitrahar era. Used to put a small antenna on the roof, which used to clear the picture by rotating it. Then many channels came and came the dish antenna. That is, an antenna with a large umbrella. We started enjoying many channels in our homes through Dish Connection. And then came the round, of a small umbrella. DTH means direct to home service. Today, different companies including Airtel, Videocon, Dish TV, Jio and Free to Air provide DTH.
If you go on the roof of a high building in a city or town, you will see many DTH antennas installed on the roofs of people. The antenna can be of any company, but you will notice that the antenna of each DTH is slanted. Have you ever thought that the antenna of DTH is always placed diagonally. Little by little everyone understands that an antenna is used for the signal. But what if putting it straight? Why is it necessary to put it diagonally?
The system works in the DTH antenna as well as in the large umbrella dish antenna. In DTH, the antenna captures the signals and converts them into pictures in our TV. This will not happen if the antenna is not mounted diagonally. Actually, due to the slanting of the DTH antenna, we are able to see TV channels clearly. Know further the reason behind this.
The reason behind its slant is its design. When a ray hits its concave surface, it does not reflect back. Due to its design, these rays are focused on its focus, which is located right in front of the Surface Medium. This feed horn receives the signals. From here the signal reaches the DTH box and then we are able to watch the broadcast program in TV.
If you put the antenna straight, what will happen?….. When the DTH antenna is placed straight, the rays coming on its surface will hit it and go back. If these rays are not focused on the focus, then the signal will not be received and we will not be able to see any program. Hope you now understand why DTH antennas are installed diagonally.
