High Gain HDTV Antennas Are Just What Your TV Needs
At the beginning of the 20th century, nobody knew about television. Nowadays, TVs can be found on every continent, even in Antarctica! Billions of people globally own that small magical box that gives entertainment for every age group and broadcasts news all around the world. Actually, in the 1940s, only several thousand people in America had TV sets in their homes. The 20th century gave birth to groundbreaking technology, and our lives wouldn’t be the same without the inventions that took place not that long ago.
Who actually invented television?
Maybe you didn’t know that mechanical televisions were invented at the beginning of the 19th century before the electronic TVs we know today appeared a century later. They were very basic compared to electronic TVs, and they worked on the principle of transmitting scanning images.
There was even a TV set that worked with the help of a rotating disk. John Logie Baird from Scotland and Charles Francis Jankins from the US were considered to be inventors.

Paul Gottlieb Nipkow from Germany also created a mechanical TV set that worked with the help of a rotating metal disk. Nipkow himself called the invention electric telescope rather than television. At the beginning of the 20th century, Boris Rosing from Russia and A.A. Campbell-Swinton from England invented a new system using cathode tubes and a mechanical scanning system. With their creativity and intelligence, they set the foundations for the technology that we know today.
Philo Taylor Farnsworth is considered the inventor of the first TV when he was only 21 years of age. He lived through his childhood years dreaming about recording moving objects and translating those images to a device through codes and radio waves. Instantly, this invention threatened the old mechanical sets that lived very shortly and eventually died.
Everyone remembers the legend Charlie Chaplin that entertained so many people with his incredible acting. But also, everyone remembers that it was only broadcasted in black and white. This is because color TV was only mentioned in the early 20th century, but nobody came up with the right technology to make that happen.
When did HDTV come into the picture?
The NTSC or National Television System Committee was formed back in 1953 to create a standard about color TVs. One year later, the first color TV made its debut in the stores. The population hugely expected the transition from black and white to a color TV, and they embraced it with open arms. During the 1960s, many people changed their TVs for this new system that provided vivid colors and showed pictures and videos more realistically. Click here to learn more about HDTV.
During the 70s and the 80s, people started to replace the old school antennas, mainly because cable TV became very popular. The next major hit was the invention of high-definition television. Early talk about HDTV took place in Japan by the Japan Broadcasting Corporation, back in 1970. A decade later, the HDTV debut took place in the US as well, and President Ronald Reagan himself introduced it to the public.
Standard Definition Television (SDTV), which provides a 480i SDTV signal, has six times lower resolution than the advanced 1080i HDTV signal. The old school TVs had a 4:3 aspect ratio, rather than the new HDTV 16:9 ratio, which closely resembles human vision. With the invention of HDTV, coding processes that were ruining the quality of the image were soon forgotten. Instead of a single component, three components were used in high-definition television, and the digital system used was the magical secret of HDTV.
How great is the importance of an antenna when it comes to television?
For sure, you have read the word “gain” in the title of this article, but do you actually know what this means? It is an indication for every antenna about how well energy is focused from a particular direction. The gain is expressed in decibels, and this value tells us how much the maximum intensity for the reception is. Usually, the gain is always the main parameters labeled on every antenna, but it shouldn’t be the primary judgment factor for the antenna’s performance. If you do some research online, you can find the perfect high gain HDTV antennas for your TV set.
When you want to buy an antenna, characteristics other than the “gain” should be considered as well. Logically, high gain values, which are around 10 decibels, are better than the lower values, but the overall performance of the antenna depends on several factors. The important thing is that the antenna you buy can be adequately installed where you live and the reception to be on a good level.
