A WiFi antenna is a device built to pick up the wireless network radio transmissions that are broadcasted from several devices such as laptops, routers or mobile phones. They are key components that are needed to pick up or radiate WiFi signals where needed.
Consider a WiFi antenna to upgrade your home or office router where you may be experiencing connectivity issues or are looking to extend the signal of your router. Antenna upgrades can sometimes be simpler and more cost-effective to fix with a new antenna, especially with home networks.
