When it comes to RF and EMI testing, selecting the right shielding solution can significantly impact the accuracy and efficiency of your results. Whether you're developing consumer electronics, working in aerospace, or testing medical devices, the right RF shield box ensures optimal signal isolation and compliance with industry standards.

1. Understand Your Frequency Requirements of the RF Shield Box

Start by identifying the frequency ranges you need to isolate. At Nova Shielding, our enclosures support a wide spectrum, from low-frequency EMI interference to high-frequency 5G and Wi-Fi signals. Knowing the signals you're working with helps us recommend the appropriate attenuation level and material for your box.

2. Define the Use Case

Ask yourself:

Are you using this for R&D or production testing?
Will it be used in a fixed lab or a mobile setup?
Do you need modular components or fixed interfaces?

These answers determine whether you need a tabletop unit, a rack-mounted solution, or a custom-sized chamber. Nova Shielding offers all three, customized to your workflow.

3. Consider I/O and Access Points

A shielding box is only as good as its I/O integrity. We offer a wide range of filtered I/O options, including USB, Ethernet, SMA, DB9, DB25, HDMI, and more. Proper isolation and shielding around these ports ensure minimal leakage and accurate testing results.

4. Ease of Operation

Our boxes feature durable yet ergonomic latching mechanisms, quick-access lids, and options for pneumatic or manual operation, important for high-throughput environments where speed matters as much as performance.

5. Future-Proof with Customization

You may not know all future testing needs today. That’s why we offer scalable and customizable enclosures that evolve with your testing demands. Need extra ports next year? A different internal lining? No problem.

There are lots of variables to consider, and we are here to help. Our custom shielding solutions provide:
