And why RF Safe still offers phone cases after 25+ years

For over 25 years, RF Safe Approved designs have held a single line: no compromises. You will never see metal loops, metal plates, or gimmicky detachable magnet systems on our products—because those “features” can increase your exposure. We didn’t pioneer anti-radiation cases in the 1990s so others could sell props; we did it to teach first principles and keep families safer.

When competitors copied our decades-old blueprint without understanding the physics, the category drifted into bad habits. That’s why QuantaCase exists today: to reset the standard and give consumers a simple way to tell genuine protection from fake.

Quick comparison: features some leading brands don’t support

The Red Flags (and why they matter)

Red Flag #1 — Metal Loops

The problem: Metal hardware near a phone’s antenna alters propagation and can detune the system.
What it means for you: Unpredictable radiation patterns and possible power ramp-ups as the phone fights to keep a link.
Bottom line: If a case adds metal where the antenna “sees” it, the designer doesn’t understand microwave systems. RF Safe never adds metal loops.

Red Flag #2 — Detachable Designs with Magnets & Plates

The problem: Big plates and magnets in “wallet-detach” cases obstruct the antenna and change the link budget.
What it means for you: When signal quality drops, phones can boost output by orders of magnitude to stay connected—exactly the opposite of “protection.”
Bottom line: Magnets/plates are dose multipliers masquerading as convenience.

Red Flag #3 — Unrealistic % Claims

The problem: “99% protection” is marketing theater. A fabric swatch in a chamber ≠ real-world body exposure.
Reality check: Protection depends on geometry, orientation, antenna health, duty cycle, and how you actually use the phone.
RF Safe policy: We’ve never sold a percent. We sell first-principles design that reduces exposure when distance isn’t possible—and we teach you how to use it.

Red Flag #4 — Unshielded Speaker Holes

The problem: Large, unshielded front-cover holes (often aimed at your ear canal) become RF windows—especially with shorter 5G wavelengths.
What it means for you: A direct path for high-frequency energy right where bone protection is thinnest.
QuantaCase fix: A shielded speaker aperture that preserves audio while keeping the front cover continuous from a shielding standpoint.

How to choose a genuine anti-radiation case

• No metal loops. No plates. No magnets.

• Shield only where it helps: between you and the phone—never 360° wraps that choke the antenna.

• Antenna-clear zones: let the radio work efficiently so it can talk quietly.

• Real-world orientation: pocket/nightstand/desk use must keep the shield toward your body.

• Honest testing: attenuation swatches are fine, but what matters is phone behavior (output) and near-body exposure in use.

The QuantaCase™ Standard (what we build—and why)

• Precisely placed front-cover shield toward the body (the only place it matters).

• No metal loops, plates, or magnets—ever.

• Shielded speaker hole for the 5G era (no “holes” in your protection).

• Ultra-thin profile: avoids detuning and unnecessary power ramp-ups.

• Antenna-clear layout: keeps the radio efficient so exposure stays lower.

• Ohmmeter-checkable: access point to verify shielding conductivity yourself.

• Single RFID-blocking slot: sensible security without turning your case into an RF choke.

• Built-in landscape stand: adds distance for streaming and reading.

• Side latch: one-finger use that naturally keeps hands away from the phone’s hot zones.

Remember: nothing beats distance. A genuine anti-radiation case is for the moments when the phone must be close. Used correctly, QuantaCase reduces exposure without making the phone fight you.

How to use it (quick guide)

• During calls: start the call, then close the front flap toward your head. Use speaker or a wired headset when you can.

• In a pocket: place the phone with the shielded cover toward your body (back pocket preferred).

• Texting/browsing: fold the flap behind the phone to shield your hand/torso and keep some distance.

• Nightstand: don’t cuddle the phone. Use airplane mode when feasible or place it away from the pillow.

Why RF Safe is still here

We happily left categories once the market could build them right (air-tubes, belly bands). We’re still making phone cases because too many “anti-radiation” designs break first principles and can be worse than no case at all. QuantaCase is the reference design we want the category to copy—correctly.
