    The power of the mobile radio can be maintained at about 25-50W. With high-frequency antenna, the communication distance can usually be about 30km. This is no match for the handheld, which also needs to buy batteries.

So what are the factors that affect the signal?

    Usually in accordance with the height > position > power, signal influence is the biggest height, higher signal farther, no height you need to find a good position without interference, no good position, can only dry split high power.
