Sennheiser GZL RG 58 - 0.5m Coaxial Cable
The Sennheiser GZL RG 58 - 0.5m is a professional-grade, 50-Ohm radio frequency (RF) coaxial antenna cable assembly. Measuring exactly 50 centimeters (1.64 feet) in length, this ultra-short patch cable is engineered for dense, clean RF bridging inside your equipment enclosures. It is primarily used to daisy-chain close-proximity wireless microphone receivers, link adjacent channels on antenna splitters, or connect a receiver directly to a front-mounted rack panel antenna kit.
Key RF Signal Architecture
True 50-Ohm Impedance Match: Professional wireless audio networks rely entirely on a uniform 50-Ohm impedance architecture. This short 0.5-meter cable guarantees a solid 50-Ohm profile from end to end, eliminating localized standing wave reflections and phase mismatches that corrupt signal paths and trigger dropouts.
Elimination of Rack Clutter: Because it spans just half a meter, this cable minimizes back-of-the-rack cable clutter. Keeping antenna lines short prevents long loops of excess wiring from dangling near electrical power strips, heavily reducing the risk of electromagnetic interference degrading your signal.
Ultra-Low Resistance BNC Connections: Both ends of the cable terminate in heavy-duty, male-to-male BNC connectors. These utilize a standardized twist-and-lock coupling mechanism to safeguard your equipment hooks against mechanical vibration, accidental tugs, or moving rack frames.

RF Signal Loss and Attenuation Metrics
Coaxial lines experience a microscopic amount of signal attenuation over distance. Because this patching segment is kept down to a tight 0.5 meters, line loss is virtually non-existent. At a standard 20 degrees Celsius environment, the attenuation curves for this specific 0.5-meter run parse as follows:
| Operating Frequency Channel | Expected Signal Loss over 0.5 Meters |
| 400 MHz (Lower UHF Segment) | Approx. 0.17 dB loss |
| 800 MHz (Upper UHF Segment) | Approx. 0.28 dB loss |
| 1000 MHz (Maximum Rating Threshold) | Approx. 0.31 dB loss |
System Implementation Guidelines
Keep Connections Clean: Because BNC connections operate at very high frequencies, microscopic bits of dust, oil from skin contact, or corrosion inside the barrel can mimic a major signal drop. Keep the internal pin contacts clean. If a rack link has been sitting unused or exposed to outdoor festival dust, blow it clear with compressed air before locking it down.
Protect the Bend Radius: Never pinch, kink, or force this cable into a tight, sharp 90-degree bend to clear a shallow rack lid. Bending the wire too sharply forces the center copper strand out of position relative to the outer foil shield. This localized physical change instantly skews the uniform 50-Ohm impedance shape, creating an RF bottleneck that bounces signal backward and reduces overall reception quality. Use smooth, looping layouts behind your gear.
