ARX Series Cable Construction and Performance
The electrical and mechanical performance of the ARX Series is determined by its conductor, dielectric, shielding, and jacket construction. Each cable uses a silver-plated copper center conductor and a low-density PTFE dielectric. The shielding structure consists of a helical silver-plated copper tape inner shield and a silver-plated copper outer braid. ARX-260, ARX-380, and ARX-520 also include an LD PTFE inner tape layer. All models use an FEP jacket.
This construction provides a nominal 50 Ω impedance, 77% velocity of propagation, capacitance of 86.8 pF/m, and shielding effectiveness greater than 90 dB. The detailed model-specific values are provided below.

ARX Series Attenuation Models
In the following equations, f is frequency in MHz and A(f) is nominal attenuation in dB/100 m. Each equation should be used only within the published attenuation reference range for its model.
ARX-150
ARX-260
ARX-380
ARX-520
These empirical models should not be extrapolated beyond the published attenuation data or used as a substitute for measured values at unlisted frequencies.
ARX Series Power Handling vs. Frequency
The following manufacturer-provided values represent maximum power-handling references at the listed frequencies. Actual permissible power depends on operating temperature, duty cycle, cooling conditions, VSWR, and the final system configuration.

ARX Series Performance Curves
The following manufacturer-provided curves complement the numerical specifications and show attenuation, power handling, amplitude stability, mechanical phase stability, and phase change rate across the corresponding frequency, bending, or temperature conditions.

Amplitude Stability During Repeated Bending
Phase Stability During Repeated Bending
Phase Change Rate vs. Temperature
Mechanical phase and amplitude stability are evaluated by monitoring the cable response during one complete rotation along the specified repeated bend radius. The temperature-related phase curve represents the corresponding static thermal test condition. Numerical PPM claims are not repeated in this category description.
