Wireless Computer Networking Antennas
In this article, we'll discuss Yagi, Ceiling Dome, and Cantennas. If you're not sure which one to choose, read on to get a better idea of what each one is capable of. But before we go any further, let's look at why each type of antenna is useful for different situations. And which one is best for your particular situation? Here's a quick overview.
Cantenna
If you're looking for a more reliable and extendable Wi-Fi signal, a cantenna for wireless computer networking is a great option. Cantennas are made from aluminum and work with wireless routers with external antennas. When radio waves interact with the wire element, the cantenna creates a signal that is sent down a pigtail cable to your computer or router.
The first step in assembling a Cantenna for wireless computer networking is to collect all of your materials. These include a 1.2 inch copper wire, an "N" connector, and a small screw. You will then need a pigtail (N-male connector) that will connect to your router or Wi-Fi card. After you've collected the materials, you'll need to drill a hole to connect the antenna to your computer. The hole should be slightly larger than the "N" connector.
The cantenna is made from an empty can. The length should be between three to six inches. If you have a can that's ridged, it may decrease the signal. Use a cantenna calculator to get an idea of the dimensions you'll need. Generally, radio waves travel at the speed of light, which is 299,792,458 meters per second. However, if you want to use a cantenna as a Wi-Fi device, you'll need to make sure the antenna has a wide range of compatibility.
Another way to build a Cantenna for Wi-Fi is to purchase a grocery-store potato chip can. A simple design like this has an ideal size, while for other frequencies, it could be impractical or ridiculously large. You can also use the formula above to make a waveguide antenna for any frequency. Keep in mind that the size of the antenna will have a huge impact on the quality of the signal.
Besides making a cantenna for wireless computer networking, you can also attach it to a WiFi range extender. If you're looking for a stronger WiFi signal, a cantenna and WiFi signal extenders will increase your range by around 20 percent. These devices are useful in situations where you don't have a direct connection to your computer. Cantennas are great for computer networks that have no Ethernet ports.
Yagi
Yagi antennas are one of the most popular types of directional antennas, used for receiving and transmitting a directional signal over long distances. This type of antenna was developed in Japan, but has since spread around the world. These low-profile antennas can be hooked up to a Wi-Fi router or access point to increase your connection's range and signal quality. A typical Yagi antenna has a radiation pattern of 45 degrees.
An excellent directional WiFi antenna helps you maximize your WiFi range when you're in an open area. This antenna is made from an aluminum alloy material and is compatible with any modem with a 1/4" external antenna port. It supports the 2.4 GHz frequency and comes with a cable. If you're a person who frequently uses the Internet at home or at work, a Yagi can be very helpful.
Alfa R36 router includes an 18dBi Yagi antenna with a 5 foot cable and an RP-SMA to N male connector. The Alfa Network 1W adapter includes a 5 foot RP-SMA to N type cable, and the Alfa G Network card and USB WiFi kit comes with mounting hardware. The Alfa R36 router's Realtek RTL8187L chipset is identical to the popular AWUS036H 1000mW USB adapter.
When choosing a wireless computer networking antenna, you must consider how many computers and other electronic devices will be connected to it. Do you have more than one location? For example, if you have multiple buildings with varying distances between each other, you'll probably need a large number of omnidirectional antennas or a large omnidirectional antenna. In the latter case, the omnidirectional antenna will be better suited to the task.
Mini Panel
There are a number of different types of WiFi Mini Panel antennas available. Some models are directional, such as the Alfa APA-M04 WiFi Mini Panel antenna. Others have an omnidirectional opening. These are great for covering a wide area, but they can't reach the back of your house. If you want your wireless computer network to cover your entire house, you can install a stronger antenna. A directional Mini Panel antenna can be installed outside your home for better signal coverage.
Yagi antennas are the most common directional antennas. Because of their directional pattern, Yagi antennas must point towards the source of the signal. A typical Yagi antenna will have a radiation pattern of 45 degrees. Mini panel antennas are low-profile and can improve WiFi signal indoors. They can be used as replacements for the rubber duck antenna that's typically attached to your router or access point. These antennas can punch through normal walls and reach hard-to-reach areas.
Regardless of the type of wireless networking antenna you choose, you should make sure it has a high dB rating. Smaller antennas are less effective for this purpose. But if you're using a laptop card with an integrated antenna, you may not get the best signal quality. You can try using one antenna, but you may need a second one if the signal source is closer. It's best to use both antennas if possible. The smallest antenna will work if it can connect to the signal source, but you should still consider the other one.
Omnidirectional antennas are best suited for office buildings and other areas with a wide range of users. Omnidirectional antennas are useful for homes and large spaces. They should be installed on the ceiling of the building. To connect it to the router or access point, a long coax cable must be run through the building. This is a great option if you're looking to improve your signal range in a large space.
Ceiling Dome
A ceiling dome is an ideal place to install your wireless computer network antennas. Depending on your needs, ceiling dome antennas may be used indoors or outdoors. Omnidirectional antennas have a greater coverage area and shorter range. They are usually mounted above a desk or cubicle and serve as signal boosters. Ceiling dome antennas resemble smoke detectors and are designed for unobtrusive installation in ceilings. These devices are also UL-listed and can be easily moved and repositioned.
For optimal signal strength, ceiling dome antennas are best used in buildings with many computers. In an office, there are often computers and printers in all directions, so omnidirectional antennas are best. These antennas are most effective for large office buildings and homes, but be aware that they require a long coaxial cable to be installed through the building. Depending on how many buildings you want to bridge, you may need two or more directional antennas.
