Testing the Smart Meter Guard
Our advice is that if you don't see real time data that shows a product blocks RF then it probably doesn't. This is why we have several real time videos showing the Smart Meter Guard blocking the RF
To test the effectiveness of the Smart Meter Guard, which is a custom Faraday cage that blocks smart meter RF waves, we performed several tests on a number of smart meters in different locations. The results were verified in each case by accurately measuring the RF waves emitted from smart meters. The RF waves were measured in micro watts per square meter (uw/M2), before and after the Smart Meter Guard was installed.
In each test we used a GigaHertz Solutions HF35C High Frequency Analyzer with a 20 decibel attenuator. The 20 decibel attenuator on the HF35C analyzer allowed us to measure the total power density output from the smart meters.
In each test, installing the Smart Meter Guard lowered the power density output of the smart meter from the 15,000 to 54,000 uW/m2 range to less than 60 uW/m2. We measured both outside of the house and inside of the house and got the same results, no RF waves.
If you don't see a live video of shielding product blocking RF it probably doesn't. This is why include several live videos of actual testing of the Smart Meter Guard blocking RF in real time. Please see our "Video" page for these live videos.

Why Radiation Doesn't Come Out the Back of the Utility Box
Your electrical utility box is made of and completely surrounded by grounded metal, including the back of the box. The only part of your electrical box that is not grounded metal is the glass part of the smart meter. The glass part of your smart meter is where the RF waves are transmitted from and they're not directional. The RF waves radiates everywhere but can not penetrate grounded metal. Once the Smart Meter Guard is installed it covers that last part of your utility box that is not grounded metal. Once the Smart Meter Guard is in place the high frequency radiation can not escape your utility box and all the radiation is contained.
Here is a simple analogy. Say you have a sound speaker and you put it in a sound proof box that has a hole in it. When you turn on the sound you heard the sound, even from the back of the box. Now, if you cover the hole in the sound proof box you the sound can not escape and you won't hear the sounds. The Smart Meter Guard basically "covers" the hole in your electrical utility box with a "Faraday" cage.
RF radiation is very similar to sound waves except it's dealing with high frequency radio waves and grounded metal.
Testing the Radiation Levels Inside the House
We have done extensive testing of the radiation levels inside the house with the Smart Meter Guard installed.

Router Guard Product Data
RF Blocking Technology Behind the Router Guard
Electromagnetic radiation is all around us. It’s invisible and is in microwaves ovens, WiFi routers, cell phones, smart meters and even in the FM and AM radio waves that pump music through our radios. But sometimes, this radiation is undesirable and downright disruptive. That’s where the Router Guard Faraday cage comes in.
The WiFi Router Guard is what’s called a “Faraday” cage in electrical terms. A Faraday cage is a metal enclosure formed by conductive material or by a mesh of such material. Such an enclosure blocks external static and non-static electric fields by channeling electricity through the mesh, providing constant voltage on all sides of the enclosure. Since the difference in voltage is the measure of electrical potential, no current flows through the space. Faraday cages are named after the English scientist Michael Faraday, who invented them in 1836. A Faraday cage operates because an external static electrical field causes the electrical charges within the cage’s conducting material to be distributed such that they cancel the field’s effect in the cage’s interior. This phenomenon is used, for example, to protect electronic equipment from lightning strikes and electrostatic discharges.
Faraday cages cannot block static or low frequency magnetic fields, such as the Earth’s magnetic field (a compass will still work inside). To a large degree, though, they shield the interior from external electromagnetic radiation if the conductor is thick enough and any holes are significantly smaller than the wavelength of the radiation. For example, certain computer forensic test procedures of electronic systems that require an environmental free of electromagnetic interference can be carried out within a screened room. These rooms are spaces that are completely enclosed by one of more layers of a fine metal mesh or perforated sheet metal. The metal layers are grounded to dissipate any electric currents generated from external or internal electromagnetic fields, and thus they block a large amount of the electromagnetic interference.
The reception or transmission of radio waves, a form of electromagnetic radiation, to or from an antenna within a Faraday cage is heavily attenuated or blocked by the Wifi Router Guard.
