It is recommended to purchase products in the 400MHz band because 400MHz walkie-talkies can have relatively shorter or thinner antennas due to the higher frequency, making them look more attractive and easier to use. Additionally, in Beijing, the 150MHz band is heavily interfered with, which severely affects communication distance. Under the same power conditions, the actual communication distance of 400MHz devices is better than that of 150MHz devices.
