✔Talk Range

The IC-4088A is designed to maximize performance and improve transmission range in the ﬁeld. However, the single most impor- tant factor in transmit range (talk power) is the surrounding envi- ronment. These radios are “line of sight” radios and as such, transmission range are influenced by the degree to which you can “see” the other communicating party. Large concrete struc- tures and heavy foliage or transmission from inside a building or vehicle will reduce the talk power range.

•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 foliage.
