tI' Talk Range
The IC-4008A is designed to maximize performance and im-
prove transmission range in the field.
most important factor in transmit range (talk power) is your
surrounding environment.
dios and as such, transmission range is influenced by the de-
gree to which you can "see" the other communicating
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. (up to
2 miles)
. Medium range: large buildings or trees blocking your line of
sight.
. Minimum range: mountainous areas or areas of heavy fo-
liage.
