DUOL «radomes» - куполы для защиты радарных и антенных систем, обеспечивают электромагнитные волны для передачи частот широкого диапазона.
DUOL manufactures inflatable radomes which protect antenna systems and radars while providing outstanding electromagnetic transmission performance throughout a broad range of frequencies including S-Band and X-Band. The following are just some of the benefits that DUOL radome can provide for an antenna system:
||DUOL radomes||Conventional radomes|
|Construction material||Inflatable, high-performance membrane||Composite material|
|Signal loss||Practically nonexistent||High, depending on the material|
|Installation time||Max. couple of days||Measured in weeks|
|Project costs||A fraction of conventional radome||Depending on size|
|Maintenance||Minimal, mostly visual inspection||Painting, etc.|
|Downtime||Minimal||Longer than with inflatable radomes|
The primary function of a radome is to protect the enclosed antenna system while having minimal effect on the transmission of the electromagnetic signal.
DUOL radomes utilize high strength materials to create the protective spherical envelope. Since it is supported by internal air pressure, the radome requires no rigid structural framework that can cause additional disruption and scattering of the electromagnetic signal. This provides the best broadband electromagnetic performance of any antenna envelope-type.
DUOL PVDF/PVF coated fabrics have been analyzed and tested for structural application to all environmental conditions. PVDF/PVF is one of the most inert and chemically stable polymers in use today and offers a broad spectrum of chemical protection.
The radome can be remotely moniterd and controlled. It is equiped with uninterrupted power supply and redundant blower system providing for fully autonomous 24/7 operation and at least 24 hour of operation in case of power outage.
DUOL radomes offer a long life cycle for lower overall costs. The PVDF/PVF coating provides superior life-long hydrophobic performance, so no reapplication of surface finish is ever required.
2-HP motors continuously operate in DUOL radome (secondary blowers and ancillary equipment as required). Furthermore, the internal air pressure from the pressure system offers constant tension, therefore, no re-tensioning of the material is required. Consequently, minimal maintenance is required for the pressure system. The robust, reliable pressurization system design means only minimal periodic prevention is required.
Installation is possible on the ground, rooftop or on pair of containers which can host the control room and the blower system. It is very simple to install (less than 1 day) and requires no specialized heavy lifting equipment. A HIAB truck which delivers it on the site is sufficient (except for rooftops). Installation over existing antenna is also possible without disasembling the antenna system.
