They can help you reach Wi-Fi hotspots that might otherwise be out of reach. Cantenna’s are a great addition to your travel case. Most people use them to replace the rubber ducky antenna’s on their wireless USB adapters connected to a laptop. Omnidirectional antennas are designed for 360 degree operation whereby a vertical dipole radiates and receives equally well on the azimuth plane (in all horizontal directions).Ĭantenna’s are mostly used as a receiving antenna for client computers. What is an omnidirectional antenna?įor starters, Wi-Fi antenna’s are either omnidirectional or directional. Gain is the amount of energy increased by the RF signal. Polarity is the orientation of the electric field (the transmission itself) from the antenna. An antenna provides three things to a radio transmitter:ĭirection refers to the shape or angle of the transmission, which ultimately describes the coverage area. So, whether you are buying an antenna or building your own, make sure it’s designed for the correct frequency band. If it does work, it will not work properly and the range will be terrible. But other factors such as channel width, frequency, and spectrum are equally important.Ī 2.4GHz antenna will not work with a 5GHz signal and vise versa. How do WiFi antennas work?įirst and foremost, frequency wavelength plays a key role in the construction of the antenna.

And with some basic knowledge about antennas, you will be better prepared to troubleshoot problems and plan your deployment. But for those of you planning to boost your range, using the right WiFi antenna can save you a lot of time and frustration. Most of you will be using the default antennas that come with your router. We’ll discuss various antenna types, how they work, cable lengths, and coupling requirements. In this section, we’re going to discuss how to increase WiFi range using the right antenna for the job.
