This 20' LMR400 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



Specifications:

  • Cable length: 20'
  • 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 1dB of signal loss. Attenuation for each frequency is below:
    • 700mhz: 0.7dB
    • 800mhz: 0.7dB
    • 1700mhz: 1.1dB
    • 1900mhz: 1.2dB
    • 2100mhz: 1.2dB
    • 2400mhz: 1.3dB
    • 2500mhz: 1.4dB
  • 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.

This wire is pretty stiff and difficult to work with but I needed to keep signal loss to a minimum. I had the electrician use an existing hole in the brick to route this through to the outside. It works well and I would buy it again.

When trying to determine which cable I needed for my Internet setup, I got help from the people at 3gstore. This cable was the exact one that made my setup work correctly. It works great with the least loss of signal strength, which is exactly what I was looking for. Helpful people, the exact right product at a great price. "Nuff said.

High quality cable. Good connectors. Well made.

Had some fairly stout coax (rg-58 I think) that was left over from an old hughes net set up. Using a yugi antenna we compared these side by side. Can't be 100% sure with the signal fluctuation but we feel we got approximately a -5 signal strength improvement using the low loss cable.

A must with the Wilson Dual Band Yagi 700Mhz - 2500Mhz (Verizon/Sprint/Alltel/AT
