When wires or cables are connected and extend from electronic devices which use radio waves, cell phones included, must be shielded or they will emit over-ambient radio frequency radiation levels. In order to subdue these levels of radiation from interfacing with delicate electronics and the biologic systems of the user of the cell phone we have a great solution. The clamp on ferrite bead which squashes the radiation from entering the users body. The bead protects harmful electro-magnetic fields from going through computer, cell phone headset and electronic wires which might come into contact with your body.
Wire Guards are the ideal add-on accessory to reduce Radio Frequency on any wired headset. Even Air-tube headsets have a wire which is often too close to the body, and a WireGuard deters the wire from becoming nothing more than an effective high frequency antenna!
The Wire Guard subdues harmful radiation from being transferred through the headset wire to the earpiece and does not affect the quality of the sound.
It’s for this reason that in order to be Radio Frequency Safe for the most prudent avoidance of RF radiation to use an air-tube headset. With this method there are no wires which can reach the users head. The ferrite offers a little more security in that it adds safety to the torso area.
Women who are pregnant or in the process of attempting to have children will want to use this bead to prevent the wire of the headset from being unprotected when coming into contact with the body.
The Wire Guard can be reused and will suppress radiation. It is a clamp on device which can be compared to that of a clam shell. It clamps over the wire of the headset just above the plug which is inserted into the phone. It consists of a ferrous composition based material. This material interfaces with those high frequencies and energies effectively subduing those while still allowing the vocal signal to pass through to the earpiece unrestricted. It is housed in a black composite and is made with nylon resins. This device fits any headset.
It works by affecting the magnetic material on a conductor. The current which flows through the conductor creates a magnetic field surrounding it. When the energy is transferred between the electronic current and the magnetic field it self-induces the conductor. In a straight wire this induction is basically 20nH per inch. By placing a magnetically absorbent material around the conductor it increases the flux density for a given field strength which in turn increases the inductance.
Basically using a cell phone with a hands-free headset that is not protected will ultimately increase the radio frequency exposure to the DNA within vital organs. Studies have shown that the likelihood of microwave radiation from a cell phone headset which is not protected can be precarious. Wire Guards have been known to prevent the potentially 300% increase in radio frequency from reaching the brain.
A major concern of using a headset for hands-free usage depends upon the placement of the phone. If the hands-free device is held near your body you must use proper protection such as pocket and belt-clip shields.
To install your ferrite bead:
- Position headset wire just above the plug into either ‘V’ Channel.
- Close one side over the other, verifying the wire passes through the opening on both sides and the side tabs lock.
- To transfer to another headset, carefully open the side tabs using a small screwdriver.
Ferrites are used in many consumer electronics to prevent interference from disruptive electromagnetic radiation, but they have limitations. Just as ferrites allow low frequency energy to pass, ferrites have a frequency band they are designed to block. Depending on the ferrites core composition, a ferrite’s performance diminishes at frequencies higher than for what it is rated.
While even the newest LTE phones may exceed a ferrite beads limitations, that same exact LTE 4G phone is also designed to operate on network frequencies where the ferrite is effective. RF Safe concludes a ferrite beads usefulness should be likened to an analogy of sunblock. It reduces exposure to a spectrum of radiation, but by no means will it block all the harmful waves/rays.
