Final answer:
Radio technicians ground antennas properly, increase transmitter power, install signal boosters, and use higher frequency bands to avoid signal transmission problems.
Step-by-step explanation:
Radio technicians adopt several measures to avoid signal transmission problems. One important factor is to ground antennas properly, as this can protect against lightning strikes and reduce electrical noise that causes interference. Increase transmitter power is another approach that can help overcome signal losses due to distance or obstacles, providing a stronger signal that can travel further and be more reliably received. Accordingly, installing signal boosters is another practical way to amplify signals, particularly in areas where the transmission is weakened. Lastly, to avoid overcrowded frequency bands, which may lead to interference, technicians can opt to utilize higher frequency bands where there is less traffic, thus providing clearer channels for communication.
