Coaxial cable Rangeful BNC male to SMA male HF400 20 m 50 Ω full copper

Rangeful HF400 coaxial cable with BNC male to SMA male connectors, 20 m length and 50 Ω impedance. Constructed with a full copper center conductor and HF400 dielectric and shielding design, the cable is intended for dependable RF signal transmission over medium distances. The 20-meter cable balances reach and manageable signal loss for test benches, antenna setups and radio equipment interconnections that require a 50 Ω transmission line with common BNC and SMA terminations.

Advantages

The full copper conductor reduces conductor resistance and improves signal integrity compared with copper-clad alternatives. HF400 construction offers consistent characteristic impedance and shielding coverage to limit external interference. BNC male and SMA male connectors provide secure mechanical connection and compatibility with a wide range of test instruments, antennas and radio modules. The 20 m length is long enough for flexible placement of equipment while remaining easy to route in lab and field environments.

Suitable for

• RF testing and measurement setups in labs
• Antenna connections for base stations, routers and ham radio
• Connecting radio transceivers, receivers and transmitters
• Temporary or permanent cabling in field installations

Key specifications

• Impedance: 50 Ω
• Length: 20 m
• Center conductor: solid full copper
• Connector type: BNC male to SMA male
• Cable type: HF400 coaxial
• Shielding: braid and foil (HF400 standard)
• Typical use: RF signal transmission with low to moderate loss over medium distances

How to use

Inspect both connector ends before use to ensure the BNC and SMA terminations are clean and undamaged. Attach the BNC male connector by aligning and pushing with a quarter-turn twist until it locks; fasten the SMA male connector by carefully threading it onto the mating SMA female jack to avoid cross-threading. Route the cable to minimize sharp bends and avoid tight coil loops; maintain bend radii recommended for HF400-type coaxial cable to prevent impedance changes. When disconnecting, use the connectors rather than pulling on the cable jacket to preserve connector integrity.

Usage recommendations

For best performance, keep cable runs as short as practical and avoid running the coaxial cable parallel to power lines or other high-noise sources. Periodically check connector coupling and inspect the cable for kinks or damage. When used outdoors or in humid environments, protect connector interfaces with appropriate weatherproofing to maintain a stable 50 Ω connection.
