• Upgrades to high gain antenna in seconds
• Order in pre-tuned bands

(1) Mopole™ antennas such as the CD91 exhibit a 4dB improvement in performance over a 3 wave whip but in pattern tests deliver only 2.0 to 2.5dB 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.
(2) Available pre-terminated with 5M RG58 cable.
Use -73 to replace -70 suffix.
