How does RG-213 differ electrically from RG-58 coax?

RG-213 has less loss at a given frequency.

  1. There is no significant difference
  2. RG-213 has less loss ✔
  3. RG-58 handles more power

Why: RG-213 is larger coax and attenuates signals less than RG-58 at the same frequency. Cable choice matters more as length and frequency increase.

Huh, didn't know that: Feed-line loss affects received signals as well as transmitted signals.

The dad joke
RG-213 lost less because it kept better track of the signal.
