RG174 silver-plated cable parameter description
1. Core parameters
parameter | Typical values | standard |
characteristic impedance | 50Ω ± 3Ω | RF standard impedance |
Outside diameter | 2.8mm | Including the overall diameter of the sheath |
Central conductor | 7×0.16mm tinned copper stranded wire | Equivalent AWG26 with good flexibility |
Insulation | PVC or PE foam | Low-cost solution (high losses) |
shielding | Tinned copper braid (coverage ≥95%) | Single-layer weaving, basic shielding efficiency |
Sheath material | PVC | Flame retardant, flexible, and limited temperature resistance |
Minimum bend radius | 3 mm (static) / 6 mm (dynamic) | The signal latency is high |
2. Frequency and attenuation
frequency | Attenuation (dB/m) | Attenuation (dB/ft) | Application scenarios |
100MHz | 0.21dB/m | 0.064dB/ft | Low frequencies are available |
500MHz | 0.48dB/m | 0.15dB/ft | 4G/LTE low-band |
1GHz | 0.68dB/m | 0.21dB/ft | Bluetooth/Wi-Fi 2.4GHz |
2.4GHz | 1.10dB/m | 0.34dB/ft | Wi-Fi/IoT tipping point |
3GHz | 1.25dB/m | 0.38dB/ft | Losses began to increase dramatically |
5GHz | 1.65dB/m | 0.50dB/ft | Wi-Fi 5 bands (use long wires with caution) |
6GHz | 1.82dB/m | 0.55dB/ft | Wi-Fi 6 bands (strongly discouraged) |
3. Electrical performance
parameter | Value |
capacitance | 101 pF/m |
Maximum operating voltage | 1500 V RMS (25°C) |
Average power capacity | 330W |
Peak power capacity | 2.5KW |
Stop the wave | ≤ 1.5:1(DC-3GHz) |
4. Mechanical and environmental characteristics
parameter | Value |
Minimum bend radius | 15mm (static) / 30mm (dynamic) |
Operating temperature range | -40°C ~ +80°C (PVC sheath) |
tensile strength | ≥ 50N |
Shielding efficiency | ≥70dB（1GHz） |
