How to set up a TV antenna for the Best Reception

A television antenna or tv aerial is a device that is used to receive electromagnetic signals from the local tv broadcast center. The broadcast center converts the audio and video into electromagnetic signal form then transmits it which, is called over the air transmission.

The antenna or concept of HDTV antenna was first invented by Heinrich Hertz in 1880. He was inspired, by the theory of scientist James Maxwell who said visible lights are an array of electromagnetic waves that can travel through the air like a cluster of waves. HIs first antenna was built with two flat steel bars connected to a rod and the rod connected to two metallic spheres which had space between them. A spark of electricity was created between the gaps by an induction coil which was connected to the spheres. This produced current in the rod. This spark between the gaps was an indication of the reception of waves.

Then during 1901 Italian scientist Marconi started to invent many antennas for both transmitting and receiving. He gave the idea that the taller the antenna better its signal transmission and reception would be for low-frequency waves. After almost five years wired signal transmission was achieved in a short distance. But this success led to designing more advanced and powerful antennas afterward. In 1926, Shintaro Uda from Japan invented the Yagi antenna. These antennas had high gains and are used nowadays for high-frequency bands due to their high gain.

In 1938 Wilmer Barrow invented the first modern Horn antenna which, also had high gains and was used for different purposes. In 1952 the first television antenna in an H shape was placed on a house roof in the United Kingdom. This was the first television antenna. This antenna was connected to large television sets which, let the user watch movies using wireless transmission. Then in 1960 satellite dish or dish antenna was introduced. Since then, antenna technology has continued to develop. In 1970 microstrip antenna was introduced which, was made with the only circuit board. Following this, PIFA or planar inverted F antenna was invented.

We can find this technology in most handheld devices. Now that is a different story. Today we will be discussing how to set up a TV antenna.

How does it work:

First, let’s get an idea of how tv antennas work. Local broadcast stations or tv station convert video and audio signals into electromagnetic waveforms. Then these signals are transmitted using over-the-air technology. The signals are then received by the television antennas which, then go through a tv signal tuner. The tuner then converts the electromagnetic signals into audio and video signals again. Then transfers it via a cable which is connected to the television.

How to set up a TV antenna step by step Process:

Setting up a television antenna is simple.

Determining the position of broadcast station:

Before buying an antenna, first, find out the position of the local broadcast station near your area. It is important because every antenna has a limited range to receive signals. By knowing the distance between your place and the broadcast station it will be easy for you to find the best antenna that is suitable for covering this distance.

Broadcast station frequency:

Every broadcast station has the frequency range that they broadcast. Antennas also support specific types of frequencies. So you have to first determine, what type of frequency the local broadcast center is transmitting. Suppose you bought an antenna that supports only high frequency, but the station is transmitting very high or ultra-high frequency then, your antenna will not work.

Digital tuner and connector:

Though most of the modern-day televisions have built-in tuners if somehow you do not have any then perhaps you will need a converter box. Also, look for an f connector for a coaxial cable connection. You can find all this information in your tv’s manual. Make sure to check it before buying the antenna.

Obstruction:

If the area where you live has hills or high-rise buildings then these can block signals. In that case, you will not get enough channels or in the worst case, the antenna will not work.

Placement:

For an outdoor antenna, always try to place it in the highest area of your building or house. Rooftop is best. The mast used for the outdoor antenna should be at least twelve feet tall for better reception. Another important thing is if the antenna is an omnidirectional antenna or directional antenna or outdoor tv antenna then it will cover one direction only. In that case, you can use an antenna rotator that will rotate the antenna to get your desired channels and tv reception or signal strength or signal reception or broadcast signal or digital tv signal or antenna signal. Avoid installing the antenna near electrical wires or trees. In the case, of an indoor antenna, place it near the window or close to an open place so that the signal does not get obstructed. You can mount an indoor tv antenna on the wall.

Ground block:

Always use and connect your coaxial cables from antenna to ground blocks. Because ground blocks save both antenna, cable, and television from lightning strikes.

Signal amplifier:

Signal amplifiers are devices that can boost low-frequency signals or weak signals for better reception. Some antennas come with signal boosters. If not then you have to buy it separately.

Waterproofing:

If somehow water leaks through the connection with the antenna and coaxial cable then the signal can become weak or even won’t work. So try to seal the connection where the cable gets in contact with the antenna. You can use sealing tape or silicone around the connection to make it waterproof. Though, some antenna comes with weather protection. You can buy antennas with protection.

Connection to television:

After performing the above tasks, channel the cable toward your tv and connect it with tv using the f port. If you want to connect several televisions then you can use a distribution amplifier. Keep the amplifier near the antenna for better performance. When everything is set try to scan the channels that are being broadcasted by your local broadcast station and navigate through every channel to make sure you are getting the exact amount of channels advertised by the antenna manufacturer.

Conclusion:

If you want to watch free tv channels and do not want to pay monthly rent for the cable network, then TV antennas are your best option. TV antennas are affordable and very easy to install. There are varieties of tv antennas available in the market. Buy the one that can satisfy you with its performance and of course it must be affordable. After buying the antenna go through this article. Hopefully, you will be able to get an idea of how to set up a tv antenna.
