This 30' LMR400-Equivalent ultra low loss cable has N-Male connectors on BOTH ends.

There are a number of applications for this cable, some of which may require special adapters/connectors to connect this cable to your equipment. Several popular uses for this cable, along with information about any connectors needed, are described below. If you aren't sure whether this cable is appropriate for your needs or whether you need additional connectors, please contact us.

  • If you are using this cable to connect an antenna with an N/Female connector to an adapter cable or amplifier with an FME/Male connector, you will need a 971107 connector to connect this cable to the adapter cable or amplifier (the other side of the cable will connect directly to the antenna)
  • If you are using this cable as an extension cable for an antenna with an FME/Female-terminated cable, you will need a 971108 connector to connect your antenna's cable to this cable. You will also need a 971107 connector to connect the other side of the cable to the adapter cable or an FME/Male amplifier.
  • If you are using this cable to connect an antenna with an N/Female connector to an amplifier with an N/Female connector, you do not need any adapters.
  • This cable is NOT recommended for use with the Indoor Portable Antenna or 12" Magnetic Mount Antenna unless a Direct-Connect Amplifier is used. Even then, unless you position the antenna in a location that has GREATER SIGNAL to begin with, you may experience too much signal loss. If you do choose to use this cable with one of those antennas, you will need a 971108 connector to connect your antenna's cable to this cable, and a 971107 connector to connect this cable to your adapter cable (or to the amplifier).

*this cable may be manufactured by either Wilson Electronics or Cellphone-Mate


  • Cable length: 30'
  • Connectors: N/Male
  • Cable diameter: 7/16"
  • N/Male connector diameter: 3/4"
  • Impedence: 50ohms

Signal Loss:

  • The amount of signal attenuation you'll see depends on which frequency you're using. This cable averages approximately 1.5dB of signal loss. Attenuation for each frequency is below:
    • 700mhz: 1.0dB
    • 800mhz: 1.1dB
    • 1700mhz: 1.6dB
    • 1900mhz: 1.7dB
    • 2100mhz: 1.8dB
    • 2400mhz: 2.0dB
    • 2500mhz: 2.0dB
  • Approximately .5dbm is lost at each connection between 2 cables
  • To prevent excessive signal loss, this cable should NOT be daisy chained with other cables! It is always better to use one longer piece of cable than to screw two shorter cables together.

Very well made. Sturdy construction. I used this with a external antenna to help pull more of the verizon signal overhead. When I need to install another setup that needs a low lose cable. I will buy again.

Improved my signal from a .93 to a .78. As good a signal as you would want.

Used this cable to connect a Mifi4620L to a 9 1/2" omni antenna. See my review of the 9 1/2" omni and Pepewave SOTG.

Your cable was easy to run and connect. I am very pleased with it.

It is LMR400 cable. Not much more to be said. Anyone who has worked in broadband antenna setups knows that this is one of the best cables you can buy. Connectors were solid and heat shrinked.

I am guessing that everything works as it is supposed to, but I have little to compare it to . .

I was suspect with this cable. Be aware that it is nearly 1/2 inch diameter. The connectors didn't seem waterproof, but with all the rain we've had the connection is good 30 Days later, so no problem so far.

This is a very substantial cable.
