Talk Range

The IC-4008E 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.

• Optimal range: wide, open areas free of obstructions.
• Medium range: large buildings or trees blocking your line of

sight.

• Minimum range: mountainous areas or areas of heavy fo-

liage.
