Audio-Technica AC100 100ft RG8 BNC Antenna Cable 50 Ohm

The Audio-Technica AC100 is a high-performance RG-8/U coaxial antenna cable engineered for long-range RF signal transmission in professional wireless environments. This 100-foot (30.48 m) cable provides a consistent 50 Ohm impedance path, minimizing signal degradation and ensuring maximum power transfer between antennas, receivers, and transmitters. It serves as a critical component for large-scale wireless microphone deployments, remote antenna placements, and precision test and measurement applications.

Superior Signal Performance and Integrity

The AC100 utilizes a heavy-duty 10 AWG stranded copper center conductor to maintain electrical conductivity over its entire 100-foot length. This large-gauge conductor, paired with a solid polyethylene (PE) dielectric, results in exceptionally low attenuation rates across the frequency spectrum. The cable exhibits a loss of only 1.5 dB per 100 feet at 100 MHz and maintains efficiency even at higher frequencies with 6.0 dB per 100 feet at 1 GHz. With a typical Voltage Standing Wave Ratio (VSWR) of less than 1.3:1, the AC100 ensures minimal signal reflection and optimal throughput for critical RF missions.

Advanced Shielding and Interference Rejection

To protect signal purity from external electromagnetic interference (EMI) and radio frequency interference (RFI), the Audio-Technica AC100 features a 95% braided copper shield. This high-coverage shielding provides a robust ground plane and prevents signal leakage, making it ideal for environments with high RF congestion. The 66% velocity of propagation ensures rapid signal timing, which is vital for maintaining phase coherence in multi-antenna arrays.

Professional-Grade Construction and Durability

Built to withstand the rigors of touring and permanent installations, the AC100 is encased in a durable black PVC (Polyvinyl Chloride) jacket with an outer diameter of 0.405 inches (10.29 mm). The cable remains functional in extreme environments, featuring an operating temperature range from -40°C to +80°C (-40°F to +176°F). Both ends are terminated with high-quality BNC Male connectors featuring nickel-plated brass bodies for corrosion resistance and secure mechanical coupling. The 4.0-inch minimum bend radius allows for flexible routing through conduits and racks without compromising the internal dielectric structure.

High Power Handling and Versatility

The AC100 is capable of handling significant power loads, supporting up to 1.1 kW at 10 MHz and 0.3 kW at 100 MHz. This power capacity, combined with a 5000 VDC dielectric strength and 2300 V RMS maximum operating voltage, makes the cable suitable for both low-power receive-only applications and higher-power transmission setups.

Primary Applications
