This circular Yagi antenna from Signull Technologies is another of our favorites. In addition to great performance ratings, it has a truly stylish design ”and isn't style what wireless security is all about? In addition, since the body of the antenna is clear, you can see the internal design. This allows you to also use the antenna as an educational tool.
In our tests, we were able to dramatically increase our signal strength while directing this antenna toward our test access point. Signull Technologies offers this antenna in three models: 8-dBi, 12-dBi (the model we tested for this book), and a 15-dBi model. The 12-dBi antenna that we tested seemed to have a sufficient performance boost, but depending on the application, the 15-dBi could be a better option. Please see Figures 1.11 and 1.12 for screenshots showing signal strengths.

Although the antenna's design is attractive with its clear body, long- term exposure to weather may prove to be a problem. This makes the antenna more useful for mounting indoors or under a protective cover. Fortunately, its great looks do not affect its performance, and as seen in Figure 1.12, the SMISMCY12 can really perform. This antenna is suitable for creating and linking wireless networks, and you should consider purchasing it.
