PRODUCTS: Radome Accessories
Accessories can be added to any radome. Typical accessory offerings include:
- Doors, Hatches and Windows
- Exterior Accessories
- Interior Accessories
- Installation Accessories
- Maintenance Accessories
- Climate Control Equipment
DOORS, HATCHES AND WINDOWS
Base Access Hatches and Doors are the used to gain access to the inside and outside of the radome. Doors and/or base access hatches are located near the base of the radome for direct entry into ground-mounted radomes or for access to catwalks on tower-mounted radomes. Sizes range from approximately 26 in x 26 in to 30 in x 78 in.
Large Equipment Doors. When large equipment needs to be moved on a regular basis, ESSCO can design access doors to meet that requirement.
Panel Removal Kits. For infrequent equipment access, it is possible to remove panels near the base of the radome. Contact ESSCO to discuss your specific requirements.
Zenith Hatches are often used on larger radomes to gain access to the upper exterior portion of the radome. The zenith hatch can also be combined with a vent for air flow by forced ventilation or natural convection via the stack effect.
A Boresight Window can be used to allow alignment of the enclosed antenna without removal of a radome panel. An optically transparent lexan window (typically less than ½" thick) can be installed in any designated radome panel.
EXTERIOR ACCESSORIES
Radomes are often equipped with an Aircraft Warning Light assembly, which marks the radome in accordance with FAA requirements or in-country requirements. The aircraft warning light includes a lightning rod and can include a maintenance rope and pulley assembly.
Forms of Lightning Protection, including a lightning arrestor, down conductors and grounding wires, are generally used on sandwich radomes. Metal space frame radomes act as a Faraday cage and do not require a separate Lightning Rod.
INTERIOR ACCESSORIES
Interior accessories such as Interior Lifting Slings, Interior Lighting and Internal Zenith Ladders make it easy to work on the enclosed antenna and help minimize antenna downtime.
INSTALLATION ACCESSORIES
Anchor Bolt Templates ensure accuracy of interface between radome and foundation; Radome Lifting Slings can lift an assembled radome on and off its foundation to reduce antenna downtime; and Installation Tool Kits assist in radome installation efforts
MAINTENANCE ACCESSORIES
For ease of periodic maintenance, ESSCO can supply Anchor Points at the radome zenith to allow for safety line attachment, Maintenance Rope and Pulley Assemblies, Climber's Harness Kits, External Rope Ladders, Panel Repair Kits and Spare Panels for any radome.
CLIMATE CONTROL EQUIPMENT
A variety of site-specific climate control systems are available for ESSCO radomes. Contact ESSCO for our Climate Control document.
Since the radome provides a protected indoor environment for the antenna, it is possible to control the environment using heaters, ventilation blowers, dehumidifiers or air conditioners. The radome itself does not require any type of climate control; it is a convenience for personnel working inside the radome.
The table below provides an overview of systems that are typically used. Please contact ESSCO to discuss your specific site conditions and equipment sizing.
