Product Description

Faraday cloth to prevent oscillation between donor and server antennas in a cellphone signal boosting system. It is 11 sq. ft. in size, or 36 inches wide by 44 inches long. Purchase also includes 1 foot sample of Faraday adhesive tape that can be used to tape multiple pieces of fabric together to created a wider RF blocking enclosure. It can be cut and sewn like standard fabric.

Just like a Faraday Cage blocks wireless telecommunication signals and EMF, this Faraday RF cloth is made of signal-reducing material that blocks electromagnetic radiation to maximum extent possible. Universal instructions to make various types of Faraday enclosures included. 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 tower or donor antenna, and inside broadcast or server antenna. This distance requirement in any cell phone booster system is to stop oscillation, or "feedback". If oscillation or feedback loop occurs, it can cause signal amplifier to reduce its output power and even power down or shut down to comply with FCC regulations that prevent damage to the mobile phone network.

If you cannot keep that minimum distance due to constraints such as limited space within house, building, etc., applying this DIY Faraday material cloth to the back side of the window antenna or any external donor antenna facing in-building broadcast antenna should do the trick.

Multiple Faraday cloth pieces can also be taped together using Faraday RF Tape or Faraday RF Patch to create wider area shield or Faraday enclosure to prevent or reduce signal strength in particular area, or direction. This radio frequency blocking cloth fabric can be cut or trimmed with scissors to fit your specific need. If using Faraday tape or Faraday patch, please take time needed to create your Faraday enclosure carefully on area that needs to be covered or made signal-proof because the strong sticky tape adhesive will make it difficult to remove easily after it is in place, or may damage this fabric.

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. Please check outside signal level in decibels before ordering. 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.

If it is too weak, 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.

Please note: 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.
