     E/M Wave. was formed in 2006 by a core team of seasoned Sales and Engineering professionals from the mobile communications antenna industry.  Several key members of the group worked together for over 15 years with the Antenna Specialists Division of Allen Telecom Group.  With combined experience of over 40 years of service with A/S, EM Wave believes that there are distinct advantages of designing and marketing innovative mobile antenna products for existing and  emerging markets.
     The mobile communications industry has changed significantly over the last 30 years, including increased operational frequency bands coupled with higher frequency spectrum. Most antenna manufacturers primarily focused on modifying scalable product for the emerging frequency bands and technologies, often overlooking opportunities to improve, or innovate, features on existing products.  By listening to customers and combining products for specific needs, we have seized an opportunity to develop enhanced products for a variety of vehicular and fixed point applications.
     The E/M Wave advantage starts with an experienced understanding of  customer expectations, coupled with innovative engineering, quality components, and competitive manufacturing, We offer our customers greater antenna value for their money!
