Antenna Testing by JEM Engineering
Testing
"Testing at JEM, and generating and analyzing the results and data were effortless with JEM's superior technical staff. I only wish all of the companies I work with had the same level of professionalism and promptness as JEM."
Mick Stwertnik, Sales Manager, NCG Company |
At JEM we understand the challenges facing antenna, microwave and communication system engineers, and we realize that accurate measurement of antenna electrical performance is critical. That's why we offer testing services from a far-field chamber (100 MHz to 40 GHz) to a near-field chamber (400 MHz to 6 GHz) (see Features & Benefits table below for details).
Options
(1) Customers can accompany their antenna product(s); or
(2) Customers can ship the product(s) to be tested.
