A WiFi antenna can boost your wireless internet connection signal, enabling a broader reach by increasing your modem and router effective range. A WiFi antenna is commonly used when you have particular areas of your house that do not receive your wireless signal, as they are located too far away from the access point. By placing a WiFi antenna nearby, you can ensure excellent coverage through multiple rooms and in some cases even out into the backyard. There are a few important things to take note of when purchasing home boosters, extenders or antennas, and with a wide range of products available it is important to make the right decision.Boosting WiFi Range
The antenna is an important component of any wireless internet configuration. It works by receiving and transmitting the WiFi signal, but some are more effective than others. It is important to take note of the antenna power gain as this will dictate how far the signal can be extended. Dipole antennas are the most commonly used antennas and these typically have a dBi rating of 2.14 or higher. A higher rating means that the antenna can transmit the signal further, as it can operate at a higher level of power. The power will double for every 3dBi so it is a good idea to get the highest dBi antenna you can.Directional and Omnidirectional Antennas
The choice between an omnidirectional and directional antenna will depend upon how you plan to use it. A simple way of explaining the difference is that a directional antenna works like a flashlight and an omni directional antenna works like a lamp. Omnidirectional antennas are usually the best option if you require extensive all round coverage but if you want to focus the signal in one particular direction then a directional antenna is the best choice.Wireless Network Compatability
Most WiFi antenna will be compatible with the major frequencies but you should always check this specification to ensure it is compatible with your frequency. Home and business Wi-Fi networks generally operate at 2.4GHz or 5GHz and most antenna will be compatible with both of these frequencies. There are also Mobile Phone Antennas available and these are compatible with a wider range of frequencies to support 3G and 4G connections. These are most commonly purchased when the original antenna has failed and needs to be replaced.
