ZION 1/4 inch corrugated RF coaxial cables are 50 ohm feeder cables available with annular or super-flexible helical copper outer conductors. Both models support frequencies up to 19 GHz, PE or LSZH jackets, and low-PIM RF transmission. Choose the cable by routing flexibility, attenuation, bend radius, jacket requirement, and installation environment.
The range includes two 50 ohm cables for different routing priorities. Choose 7101102 when lower attenuation is the main concern; choose 7101101 when a smaller bend radius is more important.
7101102
A 50 ohm cable with an annular corrugated copper outer conductor, 19 GHz maximum operating frequency, and 40 mm single-bend radius. Consider it for lower attenuation on routes that can accept a larger bend radius. Confirm PE or LSZH jacket and the required packing length.

A 50 ohm cable with a helical corrugated copper outer conductor, 19 GHz maximum operating frequency, and 15 mm single-bend radius. Consider it for compact routing and tighter turns. Confirm the acceptable attenuation, jacket type, and packing length for the project.
View Product Details →Start with the physical route, then check RF loss at the operating frequency. The outer-conductor form determines the practical trade-off between flexibility and attenuation.
Choose 7101101 for compact routing. Its helical construction allows a 15 mm single-bend radius and 25 mm repeated-bend radius; the route must still respect the specified bending limits.
Choose 7101102 when attenuation is the stronger priority. At 900 MHz, its nominal attenuation is 13.2 dB/100 m versus 18.4 dB/100 m for 7101101, but it requires a larger bend radius.
Select the jacket by installation environment and project rules. Both models offer PE and LSZH versions, but their installation and operating temperature ranges differ; specify the jacket before confirming the SKU.
Both models list a 19 GHz maximum operating frequency. Calculate the total cable loss at the actual frequency and route length, then include connector and installation losses before approving the link budget.
The annular model favors lower attenuation, while the helical model favors tighter routing. Use the table for initial selection and confirm the selected jacket, SKU, packing length, and project test requirements in the RFQ.
| Model | Outer Conductor | Jacket Diameter | Bend Radius | Attenuation at 900 MHz | Best For |
|---|---|---|---|---|---|
| 7101102 | Annular corrugated copper tube | 9.50 ± 0.20 mm | 40 mm single / 80 mm repeated | 13.2 dB/100 m | Lower-loss routes with room for wider bends |
| 7101101 | Helical corrugated copper tube | 7.50 ± 0.20 mm | 15 mm single / 25 mm repeated | 18.4 dB/100 m | Compact routes and tighter bends |
These cables fit 50 ohm RF feeder routes where shielding, low PIM, and controlled attenuation matter. The final selection must be checked against the full link budget, bend path, jacket rules, and connector system.
Use the cable as a 50 ohm RF transmission line between compatible equipment and antenna-system components. Connector type, assembly workmanship, and installed loss must be specified separately.
The 7101101 super-flexible cable is the practical option when the route contains tighter bends. It is not a substitute for ignoring repeated-bend limits or moving-cable requirements.
The 7101102 annular cable suits routes where lower attenuation is worth the larger bend radius. Confirm that the route has enough clearance before installation.
It is a compact 50 ohm RF feeder cable with a corrugated copper outer conductor. The corrugation provides mechanical flexibility while the solid outer conductor supports RF shielding and low-PIM transmission.
7101101 is the tighter-bending helical model, while 7101102 is the lower-attenuation annular model. At 900 MHz, the listed attenuation is 18.4 dB/100 m for 7101101 and 13.2 dB/100 m for 7101102.
Yes, both models list 19 GHz as the maximum operating frequency. The complete assembly must still meet the required attenuation, VSWR, connector, power, PIM, and installation limits at the intended frequency.
Do not assume that “super-flexible” means continuous-flex or robotic use. It describes the tighter routing capability of the helical corrugated design; confirm flex-cycle and motion requirements for any dynamic application.
