About WiFi Antennas
A Wi-Fi antenna acts as a magnet for wireless Internet signals, allowing electronic devices like routers, smartphones, and laptops to connect. Sometimes you need to integrate Wi-Fi antennas into devices that do not have this technology built in. When you need a wireless connection on a laptop that does not support Wi-Fi, use a USB Wi-Fi antenna, which plugs into any USB port on the device and provides near-instant access. Use a long-range Wi-Fi antenna to pick up a signal from miles away through point-to-point directional antennas. eBay sellers offer a wide variety of Wi-Fi antennas and boosters.
