Product Description

500 feet LMR-400 Plenum Cable | Wilson Pro 952002 by Wilson Electronics / weBoost.

Buy 500' LMR400 Plenum Cable supplied by Wilson Electronics' commercial cell phone signal booster division, WilsonPro. It is an ultra low loss 400 coaxial cable. It is orange in color and fire rated compliant per national NFPA requirements.

What is Plenum cable?

Plenum cable has a special fire-retardant jacket that burns at a higher temperature than typical cable. When burned, the cable does not let off toxic smoke that most cables release when burned. These characteristics make plenum cable the safest option to use in any space. This long five hundred feet plenum coax cable is very durable and high safety cable thanks to its rugged characteristics. Its ruggedness and durability enables it to be used practically anywhere, indoors or outdoors because it meets maximum safety standard possible for plenum cables.

Almost all large buildings utilize the ceiling for returning air to the central AC unit, thereby making it a plenum ceiling. This means all cables running through the ceiling need to be plenum rated cables. Our 500 ft. cables for plenums are rated to meet or exceed industry standard requirements.

What exactly is Plenum? In building construction, the "plenum" is the compartmental space that is used for air circulation in heating and air conditioning systems. It is typically between the structural ceiling and the suspended ceiling or under a raised floor. What is the standard used for manufacturing these type cables? All materials intended for use on wire and cables to be placed in plenum spaces are designed to meet rigorous fire safety test standards in accordance with NFPA 262 and outlined in NFPA 90A.

NFPA 90A is the Standard used for Installation of Air-Conditioning and Ventilating Systems. This cable for plenum spaces meets or exceeds industry standards. Please click the data sheet tab above to read detailed characteristics of this best in industry 500ft. plenum cable.


  • UL rated CMP/FT6.
  • Flexible conductor enables tight bend radius.
  • Low-loss coaxial cable for wireless applications.
  • For indoor plenum use (dropped ceilings and raised floors).
  • Meets all code requirements for installation in plenum air handling spaces.

500 ft. spool of UL rated CMP/FT6, low-loss coaxial cable is for all types of wireless applications. Its flexible conductor enables tight bend radius that works in any install. The LMR 400’s UL tested fire resistant jacket also keeps your space safe from potential hazards.

When is Plenum required and who requires it?

Plenum cable is mandated to be installed in any "air handling" space by the National Electric Code. Knowing when a space requires Plenum Cable is very important. One of the easiest ways to do this is to look into the ceiling. If you see a duct going back to the Air Hauler, then this means you have a Closed Air System. However, if there isn't a duct running back to the Air Hauler, then you have an Open-Air System, and this is a Plenum Space and will require Plenum Cable.

Important note:

Please note that although image shows a connector, it does not include one because we offer several tools to help you field terminate the cable. This helps because you don't always know exactly how much cable you are going to need until you get to the job site. With these tools you will be able to create custom lengths of cable on the site.

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.
