Details
123-14-50 is a 50 Ohm Low-Loss 240 type low-loss coaxial cable built for cellular, GPS, public-safety radio, Wi-Fi, and SCADA backhaul runs where flexibility and attenuation matter equally. The construction uses a 0.056 in solid bare copper center conductor surrounded by a foam polyethylene dielectric (0.150 in diameter) for a 1.42 dielectric constant and 83% velocity of propagation.
Shielding combines an aluminum-tape outer conductor with a tinned-copper overall braid, delivering greater than 90 dB shielding effectiveness. The 0.240 in polyethylene jacket protects the assembly across a -40 to +85 C installation, operating, and storage range. Mechanical specs include a 0.75 in minimum installation bend radius, 2.5 in repeated bend radius, 80 lb tensile strength, and 0.034 lb/ft weight.
Electrical performance: 50 Ohm impedance, 24.2 pF/ft capacitance, 5.6 kW peak power handling, and 1500 V DC voltage withstand. Attenuation is 5.3 dB/100 ft at 450 MHz, 7.6 dB/100 ft at 900 MHz, 11.5 dB/100 ft at 2 GHz, and 20.4 dB/100 ft at 5.8 GHz. Sold as bulk cable for custom RF jumpers and antenna feedlines.
