Wireless antenna maker receives funding

Wireless antenna maker said Wednesday it has secured $9.4 million in additional funding from a group of companies led by Quester, Cambridge Gateway Fund and Yasuda Enterprise Development of Japan. Antenova makes "directional antennas," for wireless networks. The antennas filter out unwanted signals, which can create interference. The company says the antennas are also good for eliminating "dead zones," or areas of no cell phone coverage.
