ZION 7/8-inch corrugated RF coaxial cables are 50-ohm feeder cables for antenna and wireless infrastructure runs. The range includes copper and aluminum outer conductors, plus standard and low-loss constructions. Start by matching the conductor material and attenuation at your operating frequency, then confirm jacket, installation temperature, bending radius, and required drum length.
Four models cover the main construction choices: copper or aluminum corrugated outer conductors, each with standard and low-loss variants. All four are specified at 50 ohms and about 27.5 mm overall diameter; use the model-specific attenuation and mechanical data to make the final choice.
NO.7101108
Copper-tube construction with a corrugated copper outer conductor, 50 ± 2 Ω impedance, up to 5.2 GHz, and a 130 mm single-bend radius. Consider it for a standard copper feeder design; confirm PE or LSZH jacket and CPR level when ordering.

Copper-tube construction with a corrugated copper outer conductor, 50 ± 2 Ω impedance, up to 5.0 GHz, and a 125 mm single-bend radius. Its published attenuation is 3.71 dB/100 m at 900 MHz and 9.81 dB/100 m at 5000 MHz.
View Product Details →NO.7101110
Smooth copper inner conductor with a corrugated aluminum outer conductor, 50 Ω impedance, a 27.50 ± 0.20 mm PE jacket, and a 120 mm single-bend radius. Use the attenuation table for the required frequency before specifying the model.

Smooth copper inner conductor with a corrugated aluminum outer conductor, 50 Ω impedance, a 27.50 ± 0.20 mm PE jacket, and a 120 mm single-bend radius. Select it when the project BOM calls for this construction and verify attenuation at the operating frequency.
View Product Details →Choose from the operating conditions outward: start with frequency and allowable link loss, then match conductor construction, jacket environment, and installation limits. The word “low loss” in a model name is not a substitute for checking the published attenuation at your exact frequency.
Use the attenuation value at the project frequency and include connector and installation losses in the link budget. NO.7101108 is specified up to 5.2 GHz, while NO.7101109 is specified up to 5.0 GHz.
Match the construction required by the site design, connector system, installation method, and project standard. Do not treat models as interchangeable until the approved connector, grounding, weatherproofing, attenuation, and mechanical limits are confirmed.
Choose the jacket by the installation environment and applicable fire requirements. PE and LSZH temperature ranges differ on the copper models; specify the required CPR level and ask for the exact SKU data sheet before approval.
Plan cable trays, entry points, and tower routing around the specified single and repeated bend radii. The published single-bend radius is 120–130 mm across this range; tighter routing needs a different cable construction rather than forcing the feeder.
Use this table for initial screening. Attenuation is shown at 900 MHz and 3000 MHz because both values are published for all four models; final cable selection should use the complete frequency table and project link budget.
| Model | Outer Conductor | Impedance | 900 MHz Attenuation | 3000 MHz Attenuation | Single Bend Radius |
|---|---|---|---|---|---|
| NO.7101108 | Annular corrugated copper tube | 50 ± 2 Ω | 3.86 dB/100 m | 7.76 dB/100 m | 130 mm |
| NO.7101109 | Annular corrugated copper tube | 50 ± 2 Ω | 3.71 dB/100 m | 7.27 dB/100 m | 125 mm |
| NO.7101110 | Annular corrugated aluminum tube | 50 Ω | 3.89 dB/100 m | 7.75 dB/100 m | 120 mm |
| NO.7101111 | Annular corrugated aluminum tube | 50 Ω | 4.15 dB/100 m | 8.25 dB/100 m | 120 mm |
These cables fit fixed 50-ohm RF feeder runs where low attenuation, shielding, and mechanical durability matter. They are not small-diameter jumpers and should not be selected without checking the connector family, route geometry, grounding, and system link budget.
Use for fixed feeder sections between RF equipment and antenna systems when the specified frequency, attenuation, power, VSWR, and PIM limits match the network design. Confirm approved connectors and installation accessories separately.
Suitable for backbone feeder runs in DAS projects when 7/8-inch cable is part of the engineered design. Indoor routes may require LSZH and a specific CPR class; verify local code and the exact ordered SKU.
Use on outdoor fixed routes only with compatible weatherproofing, grounding, supports, and bend control. The cable alone does not confirm a complete outdoor installation rating for every accessory or termination.
It is a large 50-ohm RF feeder cable with a foamed PE dielectric and a corrugated metal outer conductor. The corrugated structure provides shielding and allows controlled bending for fixed antenna and wireless infrastructure routes.
Both use copper inner and outer conductor construction, but NO.7101109 is the low-loss model and has lower published attenuation at the shared comparison frequencies. For example, it is 7.27 dB/100 m at 3000 MHz versus 7.76 dB/100 m for NO.7101108.
No. Use the exact attenuation values for the operating frequency and compare the full project requirements. For NO.7101111, request the selected-version data sheet and confirm the link budget before approval.
The answer depends on the selected jacket, fire class, temperature range, and local code. Specify PE or LSZH, the required CPR classification, installation location, and environmental conditions in the RFQ rather than approving the category generically.
A complete RFQ helps ZION match the cable construction and SKU to the installation. If some values are not yet fixed, provide the equipment list and route details so the open points can be identified.
