Smart Meters are wireless digital utility meters with additional electronic features
that allow utilities and consumers to monitor energy usage. Smart meters are
part of a new global plan to upgrade the world electrical grid to a Smart Grid to
control regional energy consumption. They are being installed where your old
electric and gas meters were located. Wireless water meters are also being
planned in many regions. Smart Meter planning in the United States is related
to the Energy Act of 2007 and administered by the US Dept of Energy, the FCC,
and each state's public utilities commission (PUC). The local utility companies
have been approved to install Smart Meters in every building that receives
utilities in most of the states such as California and Michigan. Other states, such
as Connecticut and Massachusetts, are taking a "wait and see"
approach or establishing small pilot programs, due to concerns about health,
safety, privacy, and security.
Attenuation is one of the principal indicators for
measuring the effectiveness of electromagnetic interference shielding. It
refers to the difference between an electromagnetic signal’s intensity before
shielding and its intensity after shielding. Attenuation is marked in decibels
(dB) that correspond to the ratio between field strength with and without the
presence of a protective medium. The decrease in a signal’s intensity, or
amplitude, is usually exponential with distance, while the decibel range falls
along a logarithmic scale. This means that an attenuation rating of 50 dB
indicates a shielding strength ten times that of 40 dB. In general, a shielding
range of 10 to 30 dB provides the lowest effective level of shielding, while
anything below that range can be considered little or no shielding. Shielding
between 60 and 90 dB may be considered a high level of protection, while 90 to
120 dB is exceptional. Following is RF Meter Shield's Frequency Range and related
Protection Attenuation Chart.

Smart
meter enclosures are made of grounded metal on all sides except for the front
glass (or plastic) globe. This metal enclosure acts as a RF and EMF shield and
reflects the majority of radiation through the front globe. The front glass or
plastic globe of a smart meter is where the majority of RF radiation is emitted
(in all directions). A properly installed RF Meter Shield completes a shield
around the entire smart meter (reducing radiation by over 80%). A minimal
amount of RF and EMF radiation may still escapes through main feed wires to and
from the meter. Since every installation is unique, after installing a RF Meter
Shield, if you have concerns regarding smart meter radiation entering your
home, we suggest you have your unique installation tested.
The RF Meter Shield's effective protection
against RF and EMF Radiation will last 7-10 years enduring natures elements;
such as sun, rain, snow, sleet, hot temperatures and cold temperatures.
Properly installed RF Meter Shields have
been designed to stay secure in wind gusts up to 110 MPH,
The RF
Meter Shield does not block all of the transmitting and receiving RF signals.
However, it does significantly reduce them. Low strength signals are still able
to communicate with the utility.
RF Meter Shield Model: SX1000418 fits all smart meter glass covers up to a 6.5"
diameter X 6.0" long (all known smart meters currently manufactured). The
elastic end of the RF Meter Shield can be rolled-up to snuggly fit shorter
glass covers. The existing metal enclosure housing the smart meter acts as a
reflector, shielding everything except the glass cover which is shielded by the
RF Meter Shield.
