20-6000MHz High Sensitivity Direction Finding and Monitoring Antenna

ZD-DFA-206000 is a professional20-6000MHzdirection finding antennaintegrated with high-sensitivity active monitoring functionality, engineered for high-precision radio frequency detection and monitoring applications. This tower-mounted antenna features a fully integrated active monitoring unit that delivers unrivaledomni-directional coverageon the same axis as thedirection finding antennaarray, ensuring zero interference between the two systems and continuous signal capture across the entire20-6000MHzspectrum. Adopting a 5-element interferometer design with full-size dipole elements across all four sub-bands of20-6000MHz, thedirection finding antennaachieves excellent DF sensitivity, with an ultimate angular resolution well under 1° for strong signals in most of the20-6000MHzrange, and good cross-polarisation rejection for stable reception. The integrated monitoring antenna, mounted above the high-frequency DF module, is amplified at the cable top and passively combined to maintain seamlessomni-directional coverageover20-6000MHzvia a single output connector. Compatible with 5/2-channel phase-sensitive receivers (optimised for 2-channel commutated receivers in 1-6GHz of20-6000MHz), thedirection finding antennaoffers banded high sensitivity (-20~-40dBμV/m) and vertical polarisation. Mechanically, it supports rapid deploy/stow with dust caps, withstands 160km/h wind (no ice load), and its robust structural design ensures reliable long-term outdoor operation while sustaining consistentomni-directional coverageand DF performance across20-6000MHz.
