Telewave ANT220K Discone Antenna
The Telewave ANT220K is an exceptionally rugged and wideband discone antenna, operational across all frequencies from 30 MHz to 3 GHz. Its expansive vertical beamwidth facilitates clear communication for both terrestrial and air-to-ground applications, making it a versatile choice for various communication needs.
Designed to endure the toughest conditions, Telewave discone antennas are built to outlast conventional antennas that often succumb to extreme environments. These antennas have been rigorously tested and proven in deployments both within the US and internationally, showcasing their reliability for supporting diverse voice and data services across multiple frequency bands.
The construction of each discone antenna involves Military Specification 6061-T6 solid aluminum, ensuring every unit is fully welded at all joints to maximize structural strength. This meticulous construction process guarantees the antenna's robustness and longevity.
To further enhance durability, all internal connections are housed within a rugged radome, protecting the antenna against the severest weather conditions. Additionally, the application of a TxylanTM coating on all metal surfaces shields the antenna from corrosive gases, ultraviolet radiation, salt spray, acid rain, and the abrasive impact of sand storms typical in desert environments.
The ANT220K is specifically designed for mounting on galvanized steel support pipes ranging from 1.5” to 3.5” in diameter. It comes equipped with an
ANTC482 dual clamp set, ensuring a secure and stable installation.
