Draytek 7dB High-Gain WLAN Aerial
Vigor routers equipped with Wireless LAN facilities are supplied with the standard 2 or 3dB gain aerials. A higher gain aerial provides a signal gain which can in many circumstances improve your wireless coverage/range as well as your connection speed at longer ranges, particularly where your required coverage area is currently borderline and needs a 'little extra help'.
Uni(single)directional aerials are intended for application where you want the signal in one direction only, either for increased range or for security reasons. By concentrating an aerial in one direction, both transmission strength and receive sensitivity are improved as well as benefits in avoiding interference or traffic from adjacent networks in other directions.
One, Two or Three ?
An Omnidirectional angle transmits its beam in all horizontal or vertical directionals equally (360°). A directional (or 'unidirectional') aerial concentrates its beam in one direction, with a specific beam angle. By concentrating all of the signal in one direction, the signal and receive sensitivity is stronger. This is also ideal for short-range intra-building links using WDS. Note that the unidirectional aerials actually have a considerably narrower vertical beam, hence you actually don't want your PC/client to be too close and high or low to the aerial as otherwise you can actually 'miss' the signal area.
