Sennheiser GZL RG 58 - 5M Coaxial Cable
The Sennheiser GZL RG 58 - 5M (Article Number: 700161) is a professional-grade, 50-Ohm radio frequency (RF) coaxial antenna cable assembly. Measuring exactly 5 meters (16.4 feet) in length, this cable is designed to link remote wireless receiver antennas, active directional paddles, antenna splitters, and booster components together within a live sound, theater, broadcast, or corporate AV rack framework.
Key RF Signal Architecture
True 50-Ohm Impedance Match: Wireless audio systems depend on a precise 50-Ohm impedance rating across all transmitters, receivers, antennas, and cabling. This cable enforces a clean 50-Ohm match to ensure maximum power transfer and eliminate standing wave reflections, which can degrade your wireless range and cause dropouts.
Optimized Short-to-Mid Length Run: The physical thickness and conductor architecture of standard RG 58 cable makes it perfect for local rack interconnections, short antenna extensions, or positioning passive antennas just outside a booth.
Ultra-Low Resistance BNC Connections: Both ends of the cable terminate in heavy-duty, male-to-male BNC connectors. These feature secure twist-and-lock coupling mechanisms to safeguard your links against mechanical vibration, accidental yanks, or shifting equipment carts.

RF Signal Loss and Attenuation Metrics
Coaxial cables inherently lose a small amount of signal strength over distance, which varies based on the frequency group running through them. At a standard 20 degrees Celsius environment, the attenuation curves for this 5-meter run parse as follows:
| Operating Frequency Channel | Expected Signal Loss over 5 Meters |
| 400 MHz (Lower UHF Segment) | Approx. 1.74 dB loss |
| 800 MHz (Upper UHF Segment) | Approx. 2.50 dB loss |
| 1000 MHz (Maximum Rating Threshold) | Approx. 2.82 dB loss |
System Implementation Guidelines
Avoid Excessive Cable Runs: Because RG 58 cable exhibits noticeable signal loss at longer lengths, it is not recommended to string multiple 5-meter patches together or expand past a single 5-meter segment without inserting an active antenna booster (like a Sennheiser AB 3 or AB 4) to compensate for the line drop. For longer cable lengths exceeding 5 meters, upgrade to thicker, low-loss lines like Sennheiser GZL RG 8x or RG 213.
Protect the Bend Radius: Never pinch, kink, or use tight zip-ties to secure the cable around sharp right-angle rack rails. Over-bending forces the internal center copper conductor closer to the outer braided shielding foil, altering the physical space between them. This localized change disrupts the uniform 50-Ohm impedance balance and introduces internal RF reflections that can cause intermittent signal drops. Use smooth, looping cable paths instead.
