TP513 17dBi WiFi High-Gain Yagi Antenna Yagi antenna is used to radiate the signal into the forward space. The primary purpose is to reach places where a device with a default antenna would not reach. It is designed for use on stationary objects such as buildings or houses, but it is widely used for remote connection at campgrounds, RV motorhomes, boats, or remote devices like WiFi cameras. Antenna collects the signal and sends it through the cable to a networking device. It is equipped with a pigtail N-Female connector and it is ready to connect to a device with a proper extension cable. The device needs to have a detachable external antenna connector. It may require a 50 Ohm RF coax expansion cable with N-Male connector on the antenna side and connector type that fits the device on the other side. As a rule of thumb, always use the shortest line and thickest cable to avoid signal loss. Do not use RG59/RG6 coax (75 Ohm TV cable) - signal will be seriously degraded. Directional Long Range Point-To-Point This directional antenna is designed for point to point directional wireless applications. To maximize the benefits of this antenna type, point the signal beam to a remote WiFi node. It provides the most focused 17dBi signal in a narrow horizontal and vertical beamwidth of ~25°. The distance this antenna can reach may vary based on obstacles on the antenna path to the remote WiFi node like walls, threes, and other objects. The best signal gain is when a ?direct line of sight? between the antenna and the remote location is possible.
