✔ Talk Range
The IC-446S is designed to maximize performance and im-
prove transmission range in the field. However, the single
most important factor in transmit range (talk power) is your
surrounding environment. These radios are "line of sight" ra-
dios and as such, transmission range is influenced by the de-
gree to which you can "see" the other communicating party.
Large concrete structures and heavy foliage or transmission
from inside a building or vehicle will reduce your talk power.
