CommScope FSJ1-50A 1/4 in HELIAX Super flexible 50-Ohm Coax (sold by foot)

CommScope FSJ1-50A is the 1/4-inch HELIAX SureFlex cable used when a run has to bend tightly and still stay 50 ohms. A spiral corrugated copper outer conductor and low-density foam polyethylene dielectric give it a 1-inch minimum bend radius and a jacket only 0.29 inch over the PE jacket, so it routes through racks, vehicle installs, and antenna pigtails without the kink risk of stiffer hardline. Impedance is 50 ohm ±1 ohm, velocity factor is about 84 percent, and the cable is rated to 18 GHz with a 6.4 kW peak power rating. Typical attenuation is about 1.26 dB/100 ft at 50 MHz, 2.21 dB/100 ft at 150 MHz, and 3.91 dB/100 ft at 450 MHz.

Rig Cables builds FSJ1-50A to the length you need, with genuine connectors matched to this cable (N, TNC, SMA, and UHF). It is a solid choice for short feedline jumps, duplexer and filter interconnects, public-safety and LMR jumpers, and any install where bend radius matters more than the lowest possible loss of larger HELIAX. Tell us the length and connector pair and we will cut, terminate, and test the assembly before it ships.
