QEST has contributed the primary high-frequency components to the "KuStream 1000" antenna system from TECOM Industries since the beginning of 2010. This antenna system operates in the Ku-band, and QEST has delivered more than 1000 antennas so far.

At the end of 2012, QEST signed a contract with Honeywell Aerospace for the development and delivery of Ka-band antenna apertures for Inmarsat's new broadband service, Global Xpress (GX). Serial deliveries for this Program have started mid of 2015.
