NOTE:
Above ranges are based upon line of sight and are average for normal conditions. Range depends on
location, sighting, weather, and surrounding noise level, among other factors. Use of OE-254 antenna will
increase ranges for both voice and data transmissions. Enemy jamming and mutual interference
conditions will degrade these ranges. In data transmissions, use of lower baud rate will increase range.
