RG-214S type coaxial cable is a high-quality coaxial cable known for its excellent performance in demanding environments. Here's a quick overview of its key features and applications:

Key Features:

1. Construction: RG-214S has a double silver-coated copper braid shield, providing excellent shielding effectiveness and minimizing signal loss.
2. High-Temperature Operation: It typically has a wide operating temperature range, making it suitable for use in both high and low-temperature applications.
3. Low Loss Characteristics: Its design results in lower attenuation, making it ideal for long-distance and high-frequency transmission.
4. Durability: It is rugged and often comes with a solid PE (polyethylene) dielectric, providing strength and reliability in tough conditions.
5. High Power Handling Capability: This coax can often handle higher power levels than other types due to its superior construction.

Electrical Specifications:

• Impedance: 50 Ohms ± 2 Ohms
• Capacitance: Approximately 30.8 pF/ft (101.1 pF/m)
• Velocity of Propagation: ~66%
• Maximum Operating Voltage: 5,000 volts RMS
• Attenuation (Typical):
  • 10 MHz: ~1.1 dB/100 ft
