4.5M C&KU Vehicle Mounted Carbon Fiber Deployable Kit Earth Terminal (DKET) Antenna delivers the operational flexibility and Mobile capacity, connectivity and control required to support demanding missions in remote locations. The Deployable Kit Earth Terminal (DKET) and Mobile Kit Earth Terminal (MKET) is the right solution to deliver secure,reliable communications anywhere you need to establish high-speed network connectivity.This antenna adopt high efficient Cassegrain type, and after testing each specification is better than the required specification; C-band and Ku-band feed can be exchanged to use, the user can finish the feed exchanging work within 5 minutes; We have also designed C&KU compound feed, and it’s in the process of testing, after testing is verified, we will do mass production.
