Coaxial patch cable ACT Q70025 RG-58 50 Ω, 0.25 m length

ACT Q70025 is a 0.25 m RG-58 coaxial patch cable with 50 Ω characteristic impedance, intended for short RF interconnections where consistent impedance matching is required. The compact length reduces signal loss over short runs while providing the standard electrical properties of RG-58 cable. The cable is suitable for use in laboratory environments, test benches, antenna feeds, and other situations that require reliable 50 Ω transmission for RF signals.

Advantages

The cable offers consistent 50 Ω impedance across its length and a short 0.25 m form factor that minimizes insertion loss for brief connections. Its RG-58 construction delivers predictable capacitance and attenuation characteristics typical for this cable type, and the compact size makes it easy to route in crowded setups. The cable is compatible with standard 50 Ω RF connectors and test equipment used in measurement and communication applications.

Suitable for

• Laboratory test and measurement setups
• Connecting test equipment and signal generators
• Short antenna feedlines and patching
• RF prototyping and bench interconnects

Key specifications

• Coaxial type: RG-58
• Characteristic impedance: 50 Ω
• Length: 0.25 m
• Intended use: RF signal transmission and short interconnects
• Typical electrical behavior: standard RG-58 attenuation and capacitance profile for short runs

How to use

Connect the cable between two compatible 50 Ω RF ports, ensuring connectors are firmly seated to maintain impedance continuity. Use the cable for short-distance connections only; excessive bending or stretching should be avoided to preserve electrical performance. For test setups, route the cable to minimize sharp bends and avoid running parallel to high-power conductors to reduce potential interference.

Usage recommendations

Inspect connectors before use and replace the cable if any physical damage, severe corrosion, or degraded connector contacts are observed. For measurements requiring high accuracy at higher frequencies, verify that the cable length and RG-58 characteristics meet the required insertion loss and return loss specifications for your application.
