AegisGuard Radiation Shields - The Necessary Accessory

With AegisGuard™ LS
The frequencies required for most cellular and cordless phone communication are between 100 MHz. to 5.8 GHz., however some newer cordless phones operate at frequencies well above 7.0 GHz. AegisGuard™ LS Radiation Shields have consistently been proven to provide optimum shielding protection from the radiation frequencies emitted by these and other wireless products without affecting reception or battery life by deflecting, or reflecting, the frequencies away from the body at an angle opposite of the originating source.
 
Note:Scientific reports have been published since mid-2001 addressing the health risks from frequencies far below what is required for cellular phones to communicate. All AegisGuard™ products are effective at frequencies as low as 5 Hz.

In the United States, the Telecommunications Act of 1996 prohibits state or local governments from rejecting proposed cell phone towers based on concerns over the potential health effects of radio frequency emissions, provided those emissions are within the limits established by the Federal Communications Commission. Incredibly, nobody has ever been able to demonstrate the emissions are safe.

All phone manufacturers and the World Health Organization warn consumers not to use any shielding product that claims to absorb radiation (all AegisGuard™ Radiation Shields deflect radiation). When a metal, conductive or absorption based shielding material is used, the phone must compensate for a weaker signal by increasing its output power, thus increasing its radiation emissions and battery consumption. Further, absorption based products, such as sponges, deteriorate over time and leak when they become saturated.

Most people believe that radiation is emitted from a phone's antenna or earpiece, however it is the radio system (transmitter and receiver) that generates more than four times the amount of radiation as the antenna. The radio system in most phones currently available is normally located between the display and keypad, however on some older phone models it was located within close proximity to the earpiece. On some full flip phones, it is located in the lower half of the phone by the keypad.

Heat, which serves as the foundation of SAR thermal test procedures used worldwide is also emitted from phones, however it cannot possibly provide an accurate standard for determining the health effects attributed to cellular phone radiation because none of these health effects are thermally induced.

Except for AegisGuard™ Radiation Shields, every other advertised shielding product uses a shielding material tested at frequencies below those used by most cellular and cordless phones. None of them were tested as thoroughly or for as long as AegisGuard™, including shielded cases, antenna shields and adhesive style earpiece shields, pendants, etc. Good Housekeeping magazine tested five of these types of devices and discovered they provide no protection, resulting in the United States Federal Trade Commission filing charges against companies selling coin sized radiation shields. In May, 2003, two of the companies were barred from selling these types of products in the United States.

The computer models shown at the top of this page illustrate temperature (thermal) increases in the head with and without an AegisGuard™ LS Radiation Shields being used. The digital phone is operating below the United States SAR (Specific Absorption Rate) limit and placed against the head for only 15 minutes. The cutplane through the head also illustrates that the SAR standards and calculations in use worldwide do not measure or consider an extendable antenna mast. See SAR Overview for additional information.

The amount of radiation emitted by the radio system is contingent upon its design and the strength of the signal received through the antenna from the base station. At least 40% and up to 60% is absorbed by the head and neck.

Phone manufacturers began introducing models in 1999 without an extendable antenna mast, some of which incorporate the Bluetooth, 3G, 4G and 5G standards. (AegisGuard™ shields deflect the radiation emitted by products operating at the maximum allowable frequencies of 2.497 GHz., 2.17 GHz, 3.60 GHz. and 5.80 GHz. specified by the Bluetooth, 3G, 4G and 5G standards, respectively.) Yet the entire phone body has always been part of the radio system and served as an antenna. You can perform a simple test to confirm this if your phone has a removable antenna. 

Locate an area where the signal strength shown on your phone's display is strong, remove the antenna and make a call. Depending upon your phone model, you will discover there is either little difference or no difference in the operation of your phone.
