All Resources For GORE-FLIGHT™ Microwave Assemblies, 6 Series for Civil Aircraft


Maintaining signal integrity under difficult aerospace environments is essential to the reliability of sophisticated avionics in commercial aircraft. Starting with installation and continuing through harsh flight conditions, like rapid temperature/pressure changes and potential contamination from fuels, oils, and fluids. At the same time, airframe assemblies must be both lightweight and durable to improve fuel efficiency and reduce operating costs.

In fact, we conducted independent studies and research showing that globally more than 75% of microwave/RF assemblies are frequently replaced because of damage during installation or operation. So, costs can quickly add up with replacing assemblies, extra labor, and more maintenance and downtime!


GORE-FLIGHT Microwave Assemblies, 6 Series is proven to deliver the lowest insertion loss and more reliable VSWR before/after installation, providing stable and accurate performance compared to alternative airframe assemblies. Our rugged yet flexible airframe assemblies can easily withstand rigorous routing, maintenance activities, and flight conditions ensuring life-of-aircraft performance. They’re also 17% lighter weight compared to alternative designs, which improves fuel efficiency and increases cargo.

With this high level of performance, our 6 Series reduces costly production delays, field service frequency, and the need for purchasing replacement assemblies.

Commercial aircraft manufacturers no longer have to accept the practice of replacing microwave assemblies because they get damaged during installation. A fit-and-forget philosophy is now a reality because our 6 Series provides the most cost-effective, lightweight solution that ensures avionics performance for flight crews.

Installation Simulator

Gore has long been a proponent of showing accurately how its products and technologies function in real-world environments before bringing them to market. Because nearly one-third of cable failures occur during installation, this is a crucial risk factor that shouldn't be minimized. Damaged airframe assemblies can lead to compromised signal integrity and failures over time, as well as additional testing, maintenance and replacement costs. With our Cable Installation Simulator, civil and military aircraft manufacturers can be confident they are getting a reliable cable assembly solution that withstands the rigors of installation and reduces the total cost of ownership.

"Aircraft manufacturers need reliable solutions that can be installed deep within an aircraft and left there for the life of the platform. Therefore, we want to create 'fit-and-forget' solutions that will survive the demanding environments within an aircraft," said Jim Foreman, Product Manager at Gore. "We're committed to designing next-generation products that solve key challenges, and mitigate risk for aircraft," said Paul Pino, Lead Principal Design Engineer at Gore. "To do this, we test and simulate real-world conditions to ensure that our products do what we say they will do, consistently and reliably even in harsh conditions."
