This 20' LMR240 cable has an N-Male connector on one side and an FME/Female connector on the other side.

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 do not need any adapters.
  • If you need a cable to connect an antenna with an N/Female connector to an amplifier with an N/Female connector, we recommend using one of the LMR400 cables instead (which have N/Male connectors on both sides).
  • If you need 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.
  • This cable is NOT recommended for use with the Booster 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.


Specifications:

  • Cable length: 20'
  • Connectors: N/Male and FME/Female
  • N/Male Connector diameter: 3/4"
  • Cable diameter: 1/4"
  • Impedence: 50ohms

Signal Loss:

  • The amount of signal attenuation you'll see depends on which frequency you're using. This cable averages approximately 1.9dB of signal loss. Attenuation for each frequency is below:
    • 700mhz: 1.3dB
    • 800mhz: 1.4dB
    • 1700mhz: 2.1dB
    • 1900mhz: 2.2dB
    • 2100mhz: 2.4dB
    • 2400mhz: 2.5dB
    • 2500mhz: 2.6dB
  • 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.

Cable seems durable. Worked well with the omni-directional antenna.

Tried using RG-8X this was easier and went in quicker
