75 Ohm Shielded Coaxial RF Cable with Foam PE Dielectric and PVC or PE Jacket

This offering is a 75 ohm shielded coaxial RF cable specified for low-loss RF/video signal transmission. Its construction includes a bare copper inner conductor, foam PE dielectric, and an outer conductor made of adhesive aluminum foil plus braided aluminum wire. The supplied specification covers cable construction, electrical values, attenuation, shielding, dimensions, and temperature range.

The current listing configuration provides a PVC or PE jacket selection. The specified cable construction includes a 1.02 mm bare copper inner conductor, 4.57 mm foam PE dielectric, 5.22 mm foil-and-braid outer conductor, and a 6.91 mm overall jacket diameter. The information describes the cable itself rather than a terminated assembly. No connector type, cut length, termination method, accessory package, or delivery form is stated in the supplied table

The cable is specified with 75 ohm impedance, 52 pF/m capacitance, 85% velocity, and 3000 Vrms working voltage. Return loss is above 20 dB in both VHF and UHF, while shielding effectiveness is above 80 dB. Typical attenuation, measured at 25 deg C and sea level, rises from 0.02 dB/m at 5 MHz to 0.22 dB/m at 1000 MHz. Values are also listed at 50, 211, 400, 550, 750, and 865 MHz

The cable uses a foil-and-braid shield structure consisting of adhesive aluminum foil and braided aluminum wire around the foam PE dielectric. The outer conductor diameter is 5.22 mm, and the PVC or PE jacket brings the overall cable diameter to 6.91 mm. The listed bend radius is 35 mm and the temperature range is -40 to +80 deg C. No connector interface or compatibility with particular devices is specified in the available parameter table

For selection or inquiry, confirm whether the PVC or PE jacket option is required. Buyers should verify that the 75 ohm impedance, 6.91 mm overall diameter, 35 mm bend radius, and listed temperature range match their installation needs. Attenuation should be compared at the relevant operating frequency, using the stated values measured at 25 deg C and sea level.
