Which of the following is NOT a consideration when using a mobile radio?

When using a mobile radio, one of the key considerations is the actual power output and capabilities of the equipment. Mobile radios are indeed designed to be more powerful than handheld radios, providing greater output to communicate over longer distances. However, they are generally not assumed to have higher power than fixed radios, which are installed in a fixed position and often have greater power capabilities due to their larger antennas and constant power supply. Therefore, the idea that one should assume mobile radios always have higher power than fixed radios can be misleading and is not a valid consideration in typical operation settings.

This understanding clarifies why it stands apart from other considerations such as potential interference from electronics, limited range compared to fixed radios, and dependence on battery life, all of which are crucial factors to keep in mind when utilizing mobile communication equipment in the field.
