Maintaining signal integrity under difficult aerospace environments is essential to the reliability of mission-critical systems in aircraft. Starting with continuous flexing during routing through flight conditions, like repeated shock/vibration during flight, extreme altitude/temperature changes, and harsh contaminants. 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 due to damage during installation or operation. So, costs can quickly add up with replacing assemblies, extra labor, and more maintenance and downtime!


Award-wining GORE-FLIGHT Microwave Assemblies are proven to deliver the lowest insertion loss and more reliable VSWR after installation compared to leading competitor assemblies. Our rugged yet flexible airframe assemblies can easily withstand rigorous routing, maintenance activities, and flight conditions for lifetime performance. They’re also lighter weight compared to leading competitor designs, which improves fuel efficiency and increases payload.

Our assemblies have been thoroughly tested and qualified to meet stringent defense specifications and requirements for current and future generation fixed-wing and rotary-wing aircraft. With this high level of performance, our assemblies reduce costly production delays, field service frequency, and the need for purchasing replacement assemblies.

Aircraft manufacturers no longer have to accept the practice of replacing microwave/RF assemblies because they get damaged during installation. A fit-and-forget philosophy is now a reality because GORE-FLIGHT Microwave Assemblies provide the most cost-effective, lightweight solution that ensures mission-critical system performance for pilots.

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, additional testing, and maintenance and replacement costs.

Jim Foreman
Jim Foreman, Product Manager

With our installation simulator, aircraft manufacturers can be confident they are getting a reliable microwave/RF 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."
