Beingcentre-fed and ground-plane independent, thepeak gain is on the horizon across all bandsso that high power can be delivered whereneeded.Biconical antennas can beconfigured to have bandwidthsup to 30:1. At lower frequenciesthe diameter becomesdisproportionately larger, so theslimmer hybrid-bicones can beused which have bandwidths upto 5:1.XPO2V-0.8-6.0-GF/1441- Frequencies from 100MHz to 18GHz- Ground plane independent- Vertically polarised- Elevation HPBW typically 60°- Typically 1 to 3dBi gain across the band- Excellent azimuth ripple- High power- Peak gain on horizon across bandwidthAzimuth PatternElevation PatternBicone Omni antennasThe measured azimuth pattern shown for XPO2V-0.8-6.0-GF/1441 demonstrates very low azimuth ripple,which is essential to ensure maximum area protectionThe measured elevation pattern shown for OA2-0.3-10.0V/1505 demonstrates that the peak gain is on thehorizon and remains so across all frequenciesHybrid bicone has smallerdiameter than bicone,and up to 5:1 frequencybandwidthTrue biconical elementprovides up to 30:1frequency bandwidthMulti-stacked Omni-directional antennas - New feed-through technology allowsmultiple antennas to be co-located, savingspace and shadowingTo cover very wide bands without obviousfrequency gaps, “Feed-Through” technologyhas been developed which allows severalwideband omni antennas to be ‘stacked’ so thatthey may be designed into a single housing.A stacked omni will have a single mountingpoint on a vehicle, saving space and reducingthe shadowing of one antenna with another.As a bonus, high isolation between antennasallows systems with the capability of providingoverlapping frequencies to target multiplethreats without self-jamming.- Overlapping frequencies for multipleapplications- High isolation between bands- 200W per band simultaneously- Good return loss across all bands- Optional spring with NATO mount4
