DB-3450/VRC

Shakespeare® DB-3450/VRC is a high-performance, broadband VHF/UHF tactical antenna engineered for reliable communications across the 30–88 MHz and 225–450 MHz frequency ranges. DB-3450/VRC features legacy single band mechanical and electrical performance. Shakespeare teamed up with major OEMs and military end users to produce a multi-band antenna design occupying a single radome, yet allowing significant co-site and intermod interference reduction. The design allows mechanical and electrical performance equivalent to legacy antennas and utilizes only one mounting system. The antenna’s interface reduction is gained through unique matching and choking methodologies allowing two separate feed lines up to 50dB of isolation between two antennas. The DB-3450/VRC’s small diameter radome also reduces vertical signature of multiple antennas, but provides the robust mechanical strength to thrive in hostile tactical environments. The antenna is designed to mount in the legacy mounting space available on the latest tactical vehicle configurations. Specifications were thoroughly verified by testing on the leading military proving grounds. When combined with the most recent fielded multiplexing designs, this antenna can well tolerate the RF energies produced from multiple transmitters on each band.
