PRODUCTS: Dielectric

ESSCO randomly orients multiple panels comprised of dielectric frames of fiberglass to make these spherical structures.

Applications
Suitable for EMI test facilities and low-frequency communications (<1 GHz).

Construction and Materials
In constructing our dielectric space frame radomes, we use pultruded fiberglass beams where resin-to-glass ratios are carefully controlled to optimize electromagnetic performance. Attached to each beam is a proprietary, electrically thin laminate called ESSCOLAM™, to which DuPont Tedlar® is permanently bonded specifically for radome applications.

The combination of these two materials makes for a more structurally sound radome than the low-cost wet lay-up processes traditionally employed by other manufacturers of dielectric space frame radomes.

Additional facts:

• Easy to install
• Hydrophobic coatings for enhanced performance in rain
• Customized shapes, including sheds, barns and cylindrical structures
• Not recommended for applications over 68 ft. (20.7m) in diameter

Electromagnetic Performance
ESSCO dielectric space frame radomes perform very well at frequencies below 1 GHz with performance nulls at other discrete frequencies. Properly designed tuning can enhance performance, but the Venetian blind effect can negate any advantages gained.
