• Easy to use
• No need to learn how to turn off the transmissions from the cellphone.
• Cheap and effective.

Limitations

1. If the bag is put next to a cellular antenna or a “reception amplifier,” the cellphones inside the bag might get some reception.
2. Blocks the RF radiation from the cellphone, not the ELF magnetic or electric field emitted while charging the phone.

DIY process

The process of making RF blocking curtains from the S190 is very simple and comprises the following steps:

1. Decide on the size of the curtain needed (see below).
2. Buy the fabric needed
3. Stitch the fabric and make curtains out of it (small folding on the side, larger folding on the bottom, hanging loops on top).
4. Install the bar and hang the curtains from it

About the S190 Fabric

Video demonstration or RF blocking curtain

The basic rule is to have, at least (the more the better), 50cm extra fabric from each side of the window, left, right, above, and below.
If you want the curtains to have folds, you will need more extra fabric at the side of the window and not just 50 cm.
Please see the drawings below for illustration.

Our wall and window

We will use the following drawing to simulate our selection of size for the curtains

The wrong way – too small curtains

Minimum Fabric

Top to Bottom

Full wall protection

Step 2 – order the fabric

Order the length of the fabric you need/want  from the S190 products’ page

Step 3 –  Stitch the fabric and make curtains out of it

Small fold on the side, a larger fold on the bottom, and hanging loops on top.

Step 4 – Install the curtains

Good luck…send us pictures of the curtains!

The post DIY RF BLOCKING CURTAINS WITH S190 FABRIC appeared first on For EHS By EHS.

The ENV RD-100 was born out of more than 20 years of practical experience of being an EHS person,  supporting EHS individuals and raising EMF awareness. We realized that users need a meter that is extremely simple to operate straight out of the box, yet powerful enough to deliver professional-grade diagnostics when locating radiation sources, and mitigating EMF exposure.

Dual-Mode Functionality: Tailored for Every Level of Expertise

1. Beginner Mode (Instant Awareness): The radiation level is instantly represented by 4 clear LEDs (Green, Yellow, and two Reds). The threshold levels for these LEDs are configured based on our and others understanding of the possible health risk, rather than lax government standards, giving you instant peace of mind without needing to interpret complex scientific formulas.

2. Advanced Mode (Scientific Precision): A large, detailed LCD screen displays real-time data:

   • Peak values (re-calculated every half-second) and maximum peak since power-on.

   • Average values (30 seconds average).

   • Duty Cycle measurements (the percentage of active transmission time) in RF mode.

   • Signal frequency in low-frequency magnetic (LFM) and electric (LFE) modes.

   • A 30-second history graph showing real-time fluctuations.

Key Features and Practical Benefits:

• Joint Mode (One-Screen Scan): View all three EMF types of EMF (RF, LFM, LFE) simultaneously on a single screen. This allows you to quickly scan a room/car/apartment/office and immediately spot which type of field is elevated.

• RF Modulation Display: View on the meter’s screen (and hear via the speaker) the wave shape of the RF signal over a 100ms or 0.5s window, assisting in identifying the exact nature of the wireless source.

• Data Logging via PC (Optional): Connect the meter to a PC or Android device using a specialized active USB Serial cable (sold separately) to record and analyze measurements over hours (perfect for overnight bedroom monitoring).

• Long Battery Life: Runs on 2 standard AA batteries, offering up to 20 hours of continuous operation (when using quality alkaline batteries).

• Built to Last: Comes with a custom protective carrying case for safe storage and travel.

• Made in Israel: Proudly developed, manufactured, and shipped from Israel.

Technical Specifications:

• Measurement Types: Radio Frequency Radiation(RF), LF Magnetic Fields(LFM), LF Electric Fields(LFE).

• Max Sampling Rate: 60,000 samples per second.

• Display: Graphical LCD + 4-LED quick indicator.

• Audio: Internal speaker for RF modulation feedback (RF sound signature).

• Power: 2x AA batteries.

• Warranty: 2-year limited warranty.
