TechnoLab Log Periodic Yagi
Homepage: http://www.technolab-inc.com
This Yagi antenna from TechnoLab is truly one of a kind. Its low profile and small design make it a great indoor directional antenna. In addition, by placing this antenna on the outer perimeter of a building, you can easily create building-to-building links.
Our tests revealed that this little antenna is quite capable of getting the job done. For our tests, we connected the Yagi antenna directly to our test access point and attempted to connect to it using a standard ORiNOCO PCMCIA card. We found that the antenna was fairly selective, and offered good improvement in signal strength in the desired direction. Please see Figures 1.13 and 1.14 for screenshots showing signal strengths.

We also tested the access point with a combination of one stock antenna and one TechnoLab Yagi antenna, and detected no performance degradation. This is important because there are many instances where an access point will not only be providing remote user connectivity, but also local connectivity to the network. In addition to its small size and light weight, its frequency range will allow you to use it for other applications in addition to wireless networking. Overall, the Yagi from TechnoLab is a useful antenna to add to your wireless office or campus network configuration.
