Overview

The basic function of a radome is to provide a defense between an antenna and the outside environment while simultaneously minimizing impact on electromagnetic performance. Radomes protect a wide range of ground and maritime systems for communications, weather radar, military precision tracking, fire control and other antenna systems. The proper selection of a radome can improve overall system performance, reduce downtime, and extend the antenna’s useful service life through prolonged component operation and possibly reduce antenna maintenance costs.

Adding a properly designed radome can be a huge benefit to an antenna system faced with adverse weather conditions. A radome will reduce lifecycle maintenance costs and allow for better antenna uptime during significant weather events.

We offer radome solutions capable of operating in common Air Traffic Management bands. The transmission loss prediction below is a sample of one solution developed for a specific ATM application with operating frequencies from 1-4 GHz. The transmission loss prediction takes into account radome diameter, dish diameter, as well as the ATM radome panel construction, both for the body and bolting seam.

Radomes provide weather protection and concealment.

Save Your Antenna

An antenna exposed to high winds, snow, ice, humidity, UV radiation, salt-laden air and other harsh environmental conditions results in reduced system up-time, component degradation, accelerated corrosion, projectile impacts, and reduced overall system performance. A radome isolates the antenna from these conditions, allowing operations to continue with much less downtime than experienced on a system without a radome.

The structural capability of a radome provides shelter for personnel performing operational duties and maintenance activities, and a security screen by preventing visual observation of the antenna system.

Why Infinite RCS

Infinite Technologies RCS, Inc. (IT RCS) is a world leader in the design, manufacture and installation of large ground-based radomes. We have provided radomes for many domestic and international customers using a wide variety of antenna systems in most environments on Earth. We regularly supply radomes to government entities, large prime contractors, system integrators, commercial OEMs, and various other customers . Applications include weather, ATC, Military, satellite and maritime to name a few. We have a proven product that meets, and often surpasses our highly technical customer expectations adding value and longevity to almost all antenna systems.

Our expertise stems from key personnel with years of experience analyzing existing radome systems, creating innovative design solutions, and developing a system for replacement of aging radome installations worldwide.

The extensive maintenance and repairs required on older radomes often result in downtime, reduced performance, and substantial maintenance and panel replacement costs for asset owners. IT RCS has developed viable and affordable solutions for radome fleet replacement. The radomes we manufacture are designed for a minimum service life of 20 years with a reduction in lifecycle costs up to 50%. These savings are realized without degrading performance; in fact, our products have shown substantial RF and structural performance improvements over many aging radome systems

For each application, the mechanical and RF requirements are evaluated to establish an optimum solution of configuration.

Export Restrictions

Most of our radomes are classified as EAR99 or no license required (NLR), and do not require UTAR control. IT RCS does not conduct business with entities who are not in good standing with the U.S. Government.

Shipping

Each radome is packaged in fully enclosed wooden shipping crates compliant with international shipping standards to protect the contents form damage during transportation. Most crates are sized to fit inside a standard shipping container. Optional air transport crating is possible for most radome models.

Radome Warranty & Service Life

We have confidence in the durability of our radome products. We offer a warranty against defects in workmanship for 24 months from the date of installation or 30 months from the date of delivery—whichever comes first.

The nominal service life for our randomes is 20 years. With minimal maintenance and cleaning, the service life should exceed 20 years.

Testing & Certification

We perform internal testing and material evaluation for the development of our radome materials and designs. For structural testing and material properties certifications, we utilize the services of accredited testing laboratories.

Mechanical and Environmental Considerations

Structural integrity of our radomes is never compromised. Each radome design is confirmed by rigorous analysis. All analysis is performed using recognized engineering standards. Material properties are empirically generated from test coupons manufactured with the same materials and processes used in the production environment. Mountainous terrain, gorges, ocean promontories, and special wind regions are examined for unusual wind conditions as necessary.

Standard Configuration

Our radomes are evaluated to ensurethey meet each customer’s specific requirements. As such, we have a wide range of radome models available with high wind speed ratings, greater snow and ice load capabilities, or the ability to meet other atypical environmental conditions. All configurations remain compliant with our self-imposed structural safety factors.

Radome Diameter

Truncation is the height of the radome from base to zenith expressed as a percentage of the outside diameter. Truncations up to ~90% are available. Selection of the correct truncation is critical to achieving optimum RF performance. Ideally, the center of the radome and the rotation center of the antenna should be collocated. This arrangement ensures the antenna is always looking through the radome wall uniformly on either side of the antenna phase center projection, minimizing the impact on key performance characteristics.

Sizing

Radome diameter and truncation are primarily driven by antenna size and type. Most IT RCS radomes have a spherical shape with a trunca-tion or height usually between 70% and 90% of the radome diameter.

Although the exact radome size is determined by the specific antenna, some basic assumptions can be made to aid in obtaining a rough radome size. For preliminary design estimates, the following assumptions are used.
