Our philosophy

Individual products
instead of standard products

As a technology provider, QEST sees itself as a partner of the in-flight entertainment and connectivity industry. The available in-house technologies are carefully assembled with customer and service provider in mind: to design an optimal antenna system for the desired application. This results in unique products that take full advantage of their individual qualities. Typically, QEST provides commercial series application – individual antenna development leads to the in-house production of series products.
