Audio-Technica AC12 12ft RG58 BNC Antenna Cable 50 Ohm

The Audio-Technica AC12 is a high-performance 12-foot RG58 coaxial cable engineered for reliable RF antenna connections and precision signal transmission. This professional-grade 50 Ohm cable provides a stable link between wireless receivers, antenna distributors, and remote antennas, ensuring optimal wireless system performance in demanding audio environments. The AC12 facilitates efficient RF signal distribution while maintaining low attenuation across a wide frequency spectrum.

Professional RF Signal Transmission

The Audio-Technica AC12 operates across a broad frequency range from DC to 1 GHz, making it an essential component for wireless microphone systems and RF distribution networks. The cable maintains a consistent 50 Ohm impedance, which is the industry standard for minimizing signal reflections and maximizing power transfer in RF applications. With a typical VSWR (Voltage Standing Wave Ratio) of less than 1.3:1, the AC12 ensures that signal energy reaches its destination with minimal interference.

Advanced Coaxial Construction

Built on the RG-58/U standard, the AC12 utilizes a 20 AWG stranded copper center conductor. This stranded design provides significantly greater flexibility compared to solid-core cables, allowing for easier routing in tight racks or permanent installations without compromising conductivity. The solid polyethylene (PE) dielectric maintains precise spacing between the conductor and the shield, ensuring stable capacitance of 28.5 pF/ft and a velocity of propagation of 66%.

Low Loss and High Signal Integrity

Signal preservation is critical in wireless audio, and the AC12 is designed to minimize signal degradation over its 12-foot length. The cable features a braided copper shield with 95% coverage, providing superior protection against electromagnetic interference (EMI) and radio frequency interference (RFI). Technical performance metrics include:

• Attenuation at 100 MHz: 0.59 dB per 12 feet
• Attenuation at 400 MHz: 1.26 dB per 12 feet
• Attenuation at 1 GHz: 2.22 dB per 12 feet

Robust Connector Build Quality

The AC12 is terminated with high-quality BNC male connectors on both ends. Each connector features gold-plated contacts to prevent oxidation and ensure a low-resistance electrical path over years of use. The nickel-plated connector bodies provide a rugged physical interface that resists wear during frequent mating cycles. These connectors are rated for a maximum voltage of 1400V RMS and exhibit high dielectric strength up to 2000V AC.

Durable Environmental Specifications

Wrapped in a black PVC (Polyvinyl Chloride) jacket, the Audio-Technica AC12 is built to withstand rigorous professional use. The outer diameter of 0.195 inches and a minimum bend radius of 1.95 inches allow for versatile deployment in mobile rigs and fixed studio setups. The cable remains functional across an extreme operating temperature range of -40°C to 80°C (-40°F to 176°F), making it suitable for both indoor and outdoor broadcast applications.

Versatile Compatibility and Applications

The Audio-Technica AC12 is optimized for a variety of professional RF environments. It is the ideal choice for connecting remote paddle antennas (such as the ATW-A49) to wireless receivers or antenna combiners. Beyond wireless audio, the AC12 serves as a reliable solution for test and measurement equipment and low-power antenna connections where a 50 Ohm BNC interface is required.
