Tempest-shielded doors of the future
How did we succeed in developing a door that meets TEMPEST shielding standards while also being acoustically proof? Over four posts, our specialist will guide you through this journey from concept and prototype, including all the challenges we faced, to the final solution.

According to our team’s investigation at EuCAP 2026, leaking absorbers and expensive test chambers remain concerns in the antenna testing market. ‘The solutions we provide for these topics need more awareness’, says Marc Le Roy.
Marc, one of our technical specialists, was surprised that many professionals still do not know that a basic shielding test chamber (also called a DIY chamber) often meets the requirements for antenna measurement. Marc: ‘Of course, we also offer a more traditional, premium shielding chamber for the antenna market with a full Faraday cage.’
You can see the difference between these two chambers for yourself on our Antenna Testing page via this link.
Meanwhile, our Director of Sales & Marketing, Bas de Groot, engaged visitors at our stand by asking them about the condition of their hands and shoes after a full day working in a test chamber. ‘Unsurprisingly, most testing professionals still suffer from old or traditional absorbers that leak black particles onto the floor, hands, and clothes. For this issue, we also have a solution using the closed-cell absorbers we developed for the antenna-testing market.’
More details about these closed-cell absorbers can be found on our chamber upgrades webpage.

EUCAP 2026 takes place from 19 to 24 April in Dublin, Ireland. You can meet our colleagues Marc, Uliana, Dmitriy, and Bas at the Comtest stand 16-18.
