These antennas provide greater bandwidth coverage without sacrificing antenna performance. Their no tune design eliminates the need to tune in the field, hence reducing installation costs and complexity while improving overall coverage of the desired frequencies. The integrated matching circuit is housed in a rugged, impact-resistant base for maximum durability with a tapered stainless steel highly flexible whip. The CD29 is designed to interface with standard PL259 (MBC) mobile mounts, facilitate existing installation upgrades.
