Note:

Mopole antennas such as the CD91 exhibit a 4 dB improvement in performance over a 3-wave whip but in pattern tests deliver only 2.0 to 2.5 dB of actual gain. This improvement in performance can be attributed to a lower angle of radiation and is of particular benefit to users in rugged terrain conditions and in heavily built up city areas.
