LMR-240 Cable Assembly

Low-Loss Cable Assembly for Mid-Length Antenna Runs


LMR-240 cable assembly built to order with your choice of length and 50-ohm connectors. Lower loss than LL-195 in a slimmer profile than LMR-400, suited to antenna runs of 20 to 50 feet and frequencies up to 6 GHz.

Key Features

  • Lower Signal Loss: Less attenuation than LL-195 at every listed frequency, keeping more signal at the antenna and the radio.
  • Mid-Length Runs: Best suited to cable runs of 20 to 50 ft (6 to 15 m).
  • Wideband Performance: Supports cellular, Wi-Fi, GNSS and other systems up to 6 GHz.
  • Manageable Size: 0.25 in (6.3 mm) outside diameter routes easily through vehicles, bulkheads and enclosures.
  • Built to Order: Length and connectors are specified for each assembly, with SMA, N, TNC and reverse-polarity SMA options.
  • 50-Ohm System Match: Matches the impedance of Mobile Mark antennas and standard radio equipment.
