Product Description

Faraday tape is a signal blocking tape that reduces oscillation between exterior and interior antennas in a cell phone signal booster system.

Just like a Faraday Cage blocks wireless telecommunication signals and EMF, this Faraday RF tape is made of signal-reducing material that blocks electromagnetic radiation to maximum extent possible. It helps in shielding RF signals. It blocks all types of wireless signals. For example, it blocks mobile 4G, LTE, 5G. It also works in blocking wifi 2.4 GHz, 5 GHz, etc. including cordless phone signals.

All cellular amplifier kits require specific minimum distance between outside and inside antennae to prevent oscillation, or "feedback". An oscillation or feedback loop can cause signal amplifier to reduce its output power and even cause complete power off or shut down totally to comply with FCC regulations that prevent damage to the mobile network.

If you cannot keep that minimum distance due to space or other constraints, applying this DIY Faraday material tape to the back side of the window antenna or any external donor antenna facing internal server antenna should do the trick.

It can also be used to tape multiple Faraday Fabric pieces together to create larger area shield or Faraday enclosure to prevent or reduce signal strength in particular area, or direction. The tape fabric can be cut or trimmed with scissors to fit your specific need. Please take time needed to adhere tape carefully on area that needs to be covered or made signal-proof because the strong sticky adhesive will make it difficult to remove the tape easily after it is in place.

Questions & Answers


Ask a Question
  • Will any of your products deter a neighbor using special equipment to connect with my television, WiFi, and cable tv, and Mobil devices. I have to unplug everything so they can’t use it. My devices are next to a large window. I was considering purchasing the tape to place on the window seal, or the sheet to hang on the curtain. Please help.

    Unless they connect to your devices physically, it will be hard for them to access signals emitted from your devices because the housing structure prevents most signals from radiating outside. Faraday cloth stuck on windows or placed over windows like a curtain can prevent signals escaping through window glass if that glass is not Low-E, or low-emissivity glass which usually blocks most signals from coming in and going out. However, the drawback on putting Faraday material would be that signals such as your cell signal will be blocked as well and your cell phones will have weak or no signal - unless you install a cell phone signal booster we offer with installation service to counter that problem.

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Before ordering, please check outside signal level in decibels or ensure that you can make and hold a phone call at any good spot outside where you can mount an exterior antenna. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

Kevin K. of Anderson, California gave the following review:

Website is easy to use with plain straight forward info but could have had more on testing signal strength to make sure you get a strong enough booster.

Therefore, please note that stated sq. ft. coverage is based on good signal outside. For best results: If outside signal is weak, we suggest choosing the next higher sq. ft. coverage kit. If outside signal is very weak, we suggest choosing the kit with even more higher sq. ft. range bracket. Basically, higher the sq. ft. bracket, the more powerful the signal amplifier with greater Gain as well as higher uplink and downlink output power.

If outside signal is too weak (weaker than -110 dB), submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

For non installation-included kits: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
