✔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.
