NewVHF/UHF AntennasR&SAD033V3 Omnidirectional UHF AntennaRohde & Schwarz HF VHF/UHF SHF Antennas Catalog 2012/2013The R&SAD033V3 is an omnidirectional UHF antenna for naval applications. The antenna can be used for transmit-ting and for receiving only.Eight vertically polarized dipoles are circularly arranged around a center support structure and combined to one output, resulting in an excellent omnidirectional behavior.The R&SAD033V3 can fit around mast diameters of up to 670mm. The antenna is delivered in two prefitted half-shells for easy mounting to existing masts. Even refitting to existing ship structures is possible.Key facts Excellent omnidirectionality High input power for simultaneous use of multiple radio lines Stackable antenna design Reduced RCS Protected against lightning strikes by DC grounding For naval applications225 MHz to 450 MHzCompact UHF transmitting/receiving antenna for naval applicationsR&SAD033V3 Omnidirectional UHF AntennaTypical radiation patterns at 300 MHzTypical antenna gainFrequency in MHz225 250 275 300 325 350 375 400 425 450543210123Gain in dBi0180150150120 120909030603060E planeH plane 1.00.80.60.40.20, 1567891011121310 kHz 1.5 10 100 MHz 1 1.3 GHz 10 18 26.5 40 VHF/UHF AntennasR&SAD033V3 Omnidirectional UHF Antenna Rohde & Schwarz HF VHF/UHF SHF Antennas Catalog 2012/2013Operating temperature range 30 C to +55 CMax. permissible wind speed 275 km/h (without ice deposit)180 km/h (with 30 mm ice deposit)DimensionsDiameter height approx. 1270 mm 1000 mm(50 in 39.4 in)Inner diameter approx. 670 mm (26.4 in)Weight approx. 85 kg (187.4 lb)SpecificationsFrequency range 225 MHz to 450 MHzConnector 7/16 (female), 50 VSWR typ. 2.0Gain typ. 2 dBiPolarization linear, verticalPolarization decoupling 20 dBInput power max. 600 W CWAzimuth pattern omnidirectionalMax. deviation from circularity typ. < 0.75 dBOrdering information Type Order No.Omnidirectional UHF Antenna, color: squirrel gray (RAL7000) R&SAD033V3 4091.0004.02
