BNC Cables
When working with RF equipment (radio frequency systems like wireless microphones, in-ear monitors, and antenna distribution systems), BNC cables are typically used to connect antennas, receivers, and transmitters. The most common types of BNC cables compatible with live music RF equipment are 50-ohm coaxial cables due to their impedance matching with RF systems.

Are All BNC Cables The Same?
There are various different types of BNC cables for different applications and cable lengths. Below are the most common types and some of their uses.
1.) RG58
Impedance: 50 ohms
Use case: RG58 is the standard cable for most wireless microphone and in-ear monitor systems. It’s used for connecting remote antennas to wireless receivers or antenna distribution systems. Suitable for shorter runs (up to about 20 meters) in live sound applications.
Common in: Wireless microphone systems, IEM systems, and RF antenna distribution units
2. RG8X (Mini-8)
Impedance: 50 ohms
Use case: Similar to RG58 but slightly thicker and with lower signal loss over longer distances. Ideal for runs that are a bit longer (up to 30 meters) while still maintaining solid performance in live RF environments.
Common in: Medium-distance RF setups, larger venues, or when routing antennas further away from the stage area.
3. RG213
Impedance: 50 ohms
Use case: This thicker cable is used for long-distance runs (over 30 meters) where minimal signal loss is important. Suitable for large venues or outdoor setups where antennas need to be positioned far from the stage or control room.
Common in: Large-scale tours or festival environments where wireless signal stability is crucial over long distances.
4. LMR195
Impedance: 50 ohms
Use case: LMR195 offers lower signal loss than RG58, making it great for short-to-medium runs while being more durable for repeated use in live events. It’s often used for professional RF setups.
Common in: Antenna distribution systems for professional RF systems, wireless microphones, and in-ear monitors in medium-sized venues.
5. LMR400
Impedance: 50 ohms
Use case: LMR400 is a low-loss coaxial cable suitable for longer runs (up to 60 meters or more) without significantly degrading the RF signal. Its thicker build makes it ideal for permanent installations or large-scale live music events.
Common in: Large outdoor events or long-distance antenna connections in stadiums and festival environments.
Important Considerations:
Impedance Matching: Always use 50-ohm BNC cables with RF equipment (such as wireless microphone and IEM systems), as these are designed for RF signal transmission. Avoid 75-ohm cables (like RG59 or RG6), which are used more for video applications and can cause signal degradation or interference in RF systems.
Cable Length: Longer cable runs result in more signal loss, so using low-loss cables like LMR195 or LMR400 is recommended for extended distances, especially in large live music venues or outdoor environments.
Durability: For live music, which involves frequent setup and breakdown, look for cables with strong shielding and flexibility for frequent use.
Typical Applications:
- Connecting remote antennas to wireless receivers.
- Linking antenna distribution systems to multiple wireless microphones or in-ear monitors.
- Running RF signals over longer distances in large venues without signal loss.
In summary, RG58, RG8X, RG213, LMR195, and LMR400 are all excellent options, depending on the distance, signal strength requirements, and durability needed for your RF equipment.
