Are WiFi antennas a good upgrade?
Yes. However sometimes that antenna is internal to the device and isn't noticeable. If something comes with an an external antenna, you'll need to install it. A little tip - you can buy wifi antenna extension cables if you don't like the look (or performance) of the antenna on the back of the box.

Although the subject of this series of articles is antennas specifically for Wi-Fi use, some background information about antennas in general will be helpful. This is the first in a series. An antenna is a device that radiates radio waves when supplied with electric power, and/or a device that converts radio waves into electric power. Antennas are ...
Radio waves, like all waves in the electromagnetic spectrum, are measured in frequency, and the basic unit of frequency is the Hertz (abbreviated Hz,) which is one cycle per second. Hertz is used in honor of Heinrich Rudolf Hertz, the first person to prove the existence of electromagnetic waves. The basic Hertz unit is often preceded with a multipl...
One of the simplest antennas is called a “half-wave dipole,” is a total of ½ wavelength long, and is constructed of two halves, each of which is ¼ wavelength long. Each of the two halves is fed by a separate conductor in the feedline. For the same 14.300 MHz frequency as previously mentioned, a dipole would theoretically be 10.4895 ( ½ of 20.979) m...
The orientation of an antenna with respect to the earth's surface is called its "polarization." Those that are intended for their radio waves to be oriented primarily parallel to the earth's surface are said to be "horizontal," and those that are intended for their radio waves to be oriented primarily at a right angle to the earth's surface are sai...
As previously stated, antennas transmit (and receive) radio waves better in certain directions, thereby increasing the effective radiated power (ERP) in those directions. Note that the total radiated power is not increased, but is merely stronger in one or more directions, and is weaker in other directions. Even a simple horizontal dipole has gain ...
There are five different bands used for Wi-Fi transmissions: 2.4GHz, 3.6GHz, 4.9GHz, 5GHz, and 5.9GHz. How the bands are used varies from one country to another. The most widely used is the 2.4GHz band and will be the focus of this article, but the general principles are applicable to all bands. The 2.4GHz band extends from approximately 2.4GHz to ...
The photograph below shows two Wi-Fi antennas that were removed from a 2.4GHz wireless router. The bottom antenna remains in its plastic cover and retains the hinged base that allows for it to be oriented vertically regardless of the mounting position of the router. The top antenna has been removed from its plastic cover to reveal the internal cons...
At this point, you should have an understanding of antenna fundamentals as they apply to Wi-Fi. Future articles in this series will focus on nondirectional as well as directional antennas for Wi-Fi use. Both commercially available and homebrew antennas will be discussed, and guidelines will be provided for you to construct, expand, and improve your...
Jun 21, 2023 · WiFi antennas are the unsung heroes behind robust and reliable wireless connectivity. By converting EM waves into electrical signals and vice versa, they can do the following: amplify WiFi signals; extend coverage; eliminate dead zones.
Jun 5, 2020 · There are many different reasons you might have for needing a WiFi Antenna. Some of these include: - Boosting Office or Warehouse WiFi Signal - Providing WiFi on a Campsite - Extending WiFi Signal to an Outbuilding or Shed - Connecting to a public WiFi network - Create a Personal WiFi Hotspot for Campsite WiFi - Guide
Jun 20, 2017 · Everything you need to know to get started. When it comes to choosing the right WiFI antenna for your wireless networking solutions, the abundance of variations and technical terminology can seem daunting.
Jan 10, 2022 · This wireless directional antenna uses an opening angle of 35° which enables it to locate all the AP’s in a mesh Wi-Fi network outside the premises, covering a distance of up to around 800m. For this reason, it’s commonly used for long range networks.
