The external antenna is more suitable for those who live in houses, since it is placed outside the place.
In comparison to the internal model, it has a better signal capture, as it is larger and receives less interference. Precisely for this reason it is the best option for places where the TV signal is weak.
The main advantage of the internal antenna is its size, which is reduced. It is installed together with the television set and can only capture signals from closer antennas, having a shorter range.
What is the best place to install an external antenna?
The most common installation location of the external antenna is on the roof, because this is the highest part of the buildings and thus the signal reception is better. However, it is possible to place them also on walls and balconies.
The only caveat regarding the installation of this product is due to its positioning. The antenna must always be pointed towards the transmission station. And if you don’t know where it is, just check the position of the antenna of nearby houses.

Demetrio Venicio AguiarElectrical engineer
“The biggest concern that one must have when installing an external antenna and the receiving wires (RF) is to check the presence and the distance from the electrical network (which must be at least three meters) so that there is no risk of touching the equipment to the wires. ”
How much does it cost and where to buy an external antenna?
The external antenna can be found to buy at stores that sell electrical products. If you do not know one in your city you can buy it online and some sites that sell this product are Amazon, Americanas and Mercado Livre.

Purchasing criteria: How to compare models and choose an external antenna
In order to enjoy the open TV channels, it is essential to choose a correct external antenna. This decision-making process makes all the difference and must be done with caution so as not to acquire an option inappropriate to the location or need. To help you with this we have separated below what you should take into consideration.
- Signs it captures
- Wire length
- Antenna shaping
Now we will explain each of these topics to you.
The external antenna is made in different sizes, with larger and smaller options. The larger models are the ones that have the greatest signal capture capacity, while the smaller ones have a more limited efficiency in this regard.
So, for places where the signal is low, the bigger the antenna the better, since there is more possibility of being able to watch different channels. In addition, one must also analyze what is the ideal size for the area that is available.
Signs it captures
There are different types of signals that an external antenna can pick up and each model has a capacity. There are versions that only reach UHF and VHF signals, while others are more complete and transmit VHF, UHF, FM and HDTV signals.
The acronym UHF stands for Ultra High Frequency, which is an ultra high frequency. It is widely used by television channels and is recommended for urban areas.
The acronym VHF stands for Very High Frequency, which is a very high frequency used by radio stations. This is ideal for remote and rural areas. The acronym HDTV is related to high definition TV, while FM refers to radio.
Therefore, when choosing an antenna, check which of these signals the model can capture and see which one best suits your needs.
Another important point to be considered when buying the external antenna is the length of the wire that accompanies it. It should be neither too long nor too short, as these two situations will get in the way during installation.
Therefore, before purchasing the antenna, measure the distance between the television and the place where it will be installed.
In order to ensure greater durability of the antenna and avoid accidents it is important that it is manufactured with resistant materials.
Therefore, check that the antenna structure is strong and rigid and that it is made with resistant raw materials. In addition, it is essential that this material does not rust, as this product will be exposed to sun and rain.
