Vehicular Faraday Effect
Increased RF radiation inside a vehicle
Because most vehicles have metal roofs and largely come with factory tinted glass, your vehicle can act as a Faraday cage and concentrating reflector, amplifying RF wave density like a microwave oven, not letting the RF radiation escape through the metal body and tinted glass, and then concentrating the microwaves into your body at much higher EM intensities. It’s highly recommended you use antenna kit or car kit to wave guide (transport) the RF Radiation outside the vehicle to prevent amplification of the microwave effect.
Radiation gets trapped in your car via The Faraday Effect. Research has now shown that use of the cell phones inside a car, without a properly mounted car antenna, can amplify and increase the radiation levels by up to ten times (x 10)
Using your cell in the car is not only a hazard of not paying attention to the road. Tests, we at RF Safe have done, conclude none of the cell phone protection products do much good when using a cell phone in a metal enclosed vehicle.
YOU MUST USE AN EXTERNAL MOUNT ANTENNA to send and receive RF OUTSIDE OF THE VEHICLE!
Many newer phones do NOT support the use of hard wired external mount vehicle antennas.
Regardless of cell phone make or model, to keep a cell phone operating at its lowest power out-put level (when several cell phones could be in a vehicle at the same time). The best you can do is install a “Cell Phone Car Mount Passive Repeater Antenna”. This will keep any smartphones inside a vehicle from using their highest levels of RF radiation to communicate with a cell phone tower when a Faraday effect is the cause of the weak signal connection.

Often you will take your cell phone into different environments, some of which like small metal enclosed areas effect the operation of your cell phone. These environments often cause the cell phone to operate at it’s highest power output levels and can amplify EMF power densities surrounding the cell phone user.
This Environment includes: Cars, Buses, Motor Homes and any other place you find yourself inside & in close proximity to conductive walls that reflect microwave emissions.
Simply put, conductive surroundings act as concentrating reflectors “Like The Cooking Cavity Of A Microwave Oven” When inside a metal enclosure, Radio Frequency Radiation (RFR) gets trapped inside the conductive walls creating what is scientifically called a “Faraday Cage”
A Faraday Cage, named after the person that discovered it, DR. Michael Faraday (1791-1867) Known as the inventor of modern EMF (Electromagnetic Field) principles.
The Faraday Cage Effect means that the electric charge on a conductor sits on the outer surface of it, demonstrating that radio waves cannot penetrate a Faraday cage via creating a charged reflective barrier blocking rf radiation.
