Which of the following statements is not true about the RG58 coaxial cabling standard?
  1. The impedance of RG58 is 50 Ohms.
  2. The diameter of RG58 is 0.195 inches.
  3. RG58 is terminated with BNC connectors.
  4. RG58 is terminated with F-type connectors.
Explanation
Answer - D - The statement that is not true about the RG58 coaxial cabling standard is that it is terminated with F-type connectors.

Key Takeaway: RG-58 cable has a characteristic impedance of 50 Ω. RG-58 cable is used as a generic carrier of signals combined with BNC connectors. RG-58 provides a maximum segment length of 185 meters. It can be used for moderately high frequencies. Its signal attenuation depends on the frequency, e.g. from 0.11 dB/m at 50 MHz to 1.4 dB/m at 2 GHz.
