C WDA series antennas are optimized for both broadband and high gain performance. These antennas are ideally suited for use with frequency hopping radios and wideband jammers where tuning or band switching is difficult and high gain omnidirectional performance is essential. The sealed radome offers mechanical stability and environmental protection. The antenna elements in a WDA antenna are arrayed and center-fed using a unique method (patent pending) of feeder cable arrangement which creates superb wideband performance with few compromises. OVP, OHP and RSA series high gain Omni antennas are used in a wide variety of applications including communication base stations (ground-to-air, point-to-point or mobile communication), Electronic News Gathering (ENG), MMDS and radar systems. Several models are enclosed in special radomes optimized for airborne applications. WDA-97 & WDA- Only linearly polarized omnis are included in this datasheet. High gain circularly polarized omnis for mobile satellite communications and other applications are described in a separate datasheet on Helical Antennas. OVP series antennas include one or more vertically polarized dipoles mounted on a common axis and integrated into a dielectric radome. Multiport OVP antennas have at least db isolation between ports. An internal matching network keeps all antenna parts at DC ground potential. STA series super turnstile antennas are designed to provide omni-directional coverage for communication and spectrum surveillance in the VHF and UHF bands. The super turnstile design allows complete frequency coverage of the VHF/UHF commercial broadcast bands using a single antenna. SWA 7 STA series antennas offer low to medium gain, low VSWR, and wide frequency bands for transmit applications. By combining single turnstile elements, higher gain can be achieved. An omnidirectional gain of up to dbi can be achieved with a multiple bay antenna. The design is such that from one to eight bays can be constructed on a single modular mast. One or more super turnstile elements, each covering a different frequency band, can be used in tandem on a single mast to effectively span much wider frequency ranges.
