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

Other benefits:

24/7 operation regardless of weather conditions
Cover all sizes of the antenna systems
Flexible installation options. Easy to cover also existing antenna systems
Operation on remote locations with remote control
Preserves critical system alignments, thus ensuring predictability, repeatability, consistency and reliability
Improved pointing and tracking accuracy
Reduced operating and maintenance costs
Reduces antenna and pedestal costs, as they will be housed in a zero-wind environment
Minimized system downtime
Extended system & component life
Provided concealment during system upgrades (for those concerned with security)

Unsurpassed RF Performance

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.

Extreme Environmental Protection

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.

Proven Reliability

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.

Low Life-Cycle Cost

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.

Reliable pressurization system

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.

Flexible installation options

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.
