We have been dealing with antennas close to 10 years now (adjusting and modifying your terrestrial TV Yagi antenna 20 years ago doesn’t count!). Having access to wide range of antenna from factories in the far east allow us to choose suitable antenna for our project and product. But in order to get the antenna with the specifications that we really wanted, one has to go through many iterative selection process to reach that goal. Prior to the release of the Mini Ultra Pro, we have been engaged in a year long wireless sensor network project in Australia that runs in the 915 MHz ISM band. We thought having already tested variety of antenna at 915 MHz band, selecting antennas for other frequency would be as easy as specifying the requirements and specifications to our antenna supplier. Boy oh boy, we were so wrong…
