Product Description

Professional grade self-bonding non-adhesive silicone tape adheres only to itself, creating a completely air, dust, and water-tight seal. Silicone waterproofing tape can be easily removed, leaving no sticky residue behind.

This waterproof tape is impervious to temperatures from -65 degrees fahrenheit to +500 degrees fahrenheit. It is also impervious to most chemical solvents. This pro-grade self bonding silicone tape can be used in almost any environment indoors or outside to make connections like cable with connector weatherproof.

This heavy-duty 30 mil silicone water proofing tape is up to 50% thicker than other weather proof premium silicone tapes. Extra thickness of this weatherproofing tape means better protection for rough, sharp and uneven surfaces without applying extra layers. A thicker weather proofing tape provides more abrasion resistance and better insulation. This silicone tape is up to 50% wider than most other brands for faster wrapping and fewer seams.

This water proof tape is perfect for protecting CATV & RF coaxial antenna connectors and electrical plugs from damaging moisture, this premium tape is 1.5" wide, 30 mil thick and each 15 ft. roll can cover approximately 6 typical connections.

Questions & Answers


Ask a Question
  • How long to seal? Will this stick to wet surface?

    No, it only sticks to itself or other similar silicone surfaces (rolling over method makes it stick to itself). It will stick to itself if it is wet, but we suggest you dry the tape because it will stick better when dry. Call us and tell us more about your application if you need more help regarding your particular situation. Thank you.

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.
