Application example of electromagnetic wave absorption equipment: Electromagnetic wave shield tent-type simple anechoic chamber.

Application example of electromagnetic wave absorption equipment: Electromagnetic wave shield tent-type simple anechoic chamber.

We offer a shielded tent-type simple radio wave anechoic chamber that is inexpensive, easy, and quick to install!

Generally, anechoic chambers are perceived as having a large scale, high installation costs, and ongoing maintenance expenses. However, our electromagnetic shield tent-type anechoic chamber offers a proposal to construct an anechoic chamber in a cost-effective and easy manner, similar to a small anechoic box. In particular, it is suitable for cases where strict RF characteristic testing or antenna evaluation is not conducted, such as for radio law measures, protocol testing, function testing, and interoperability testing. It meets the needs of those who do not require a full anechoic chamber but desire a simple anechoic chamber. Our product utilizes high-performance shielding materials that combine shielding performance, cost-effectiveness, and lightweight properties. Due to its tightly packed seams, it maintains high shielding performance while being affordable and lightweight, allowing for the safe construction of large spaces on a low budget. Its lightweight design and ease of assembly, disassembly, and relocation mean it can be set up in various locations without difficulty.
