Description

Features: The antenna can easily be upgraded to a high gain antenna in seconds, by unscrewing and replacing the whip section. The antenna is ordered pre-tuned to a specific band. • Performance – provides 4 dB improvement over 3 wave even when mounted on a roof rack or gutter mount • Quality construction – choke assembly is handcrafted from solid brass and chrome-plated • Ideal on emergency service vehicles elevating the antenna above lights and sirens • Upgrades to high gain antenna in seconds • Order in pre-tuned bands • Can be used with a variety of mounts. See accessories section for options. (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 preterminated with 5M RG58 cable. Use -73 to replace -70 suffix.
