Which radio system has the most powerful transmitters and the most sensitive receivers?

• A. Mobile radio
• B. Base/fixed station
• C. Consolette radio
• D. Handheld radio

Answer: (B)

Fixed base stations are built to cover large areas and stay tied to a reliable power source. Because of that, they can use high-power transmitters and large, high-gain antennas, and their receivers are designed for maximum sensitivity to detect weak signals in noisy environments. In contrast, mobile radios in vehicles have to balance power with vehicle power and cooling, and handheld radios are even more limited by battery life and compact hardware, so their transmit power and receiver sensitivity are lower. A consolette is a dispatch console that interfaces with the base system, not a separate setup with greater inherent power or sensitivity. So, the radio system with the most powerful transmitters and the most sensitive receivers is the base/fixed station.
