Mopole antennas such as the CD93-72-70 has been shown to exhibit a 6.5 dB improvement in received signal level in the field when compared to a ¼ wave whip however in pattern tests exhibit only 1.5 to 2 dB over a ¼ wave (equivalent to 1.5-2 dBi). This improvement in performance can be attributed to a lower radiation angle level of these ground independent antennas.
