In a groundbreaking move to expand access to critical inflight connectivity (IFC) expertise, the Seamless Air Alliance (SAA) has publicly released the Antenna Buyer Handbook, a comprehensive guide designed to support airlines, OEMs, and suppliers in navigating the increasingly complex process of selecting satellite antennas for onboard connectivity systems.
This is the first time the Seamless Air Alliance has made a technical document of this depth available to non-members, marking a significant milestone in the organization’s mission to drive innovation and transparency across the aviation connectivity ecosystem.
The Antenna Buyer Handbook addresses the rapid evolution of satellite technologies, including the rise of Non-Geostationary Orbit (NGSO) networks such as LEO, MEO, and HEO systems. It provides an in-depth look at how these networks impact antenna design, integration, and long-term system performance. Topics covered include antenna categories, system architecture, RF performance, installation challenges, aerodynamic drag, reliability, and multi-network interoperability.
“Choosing the right antenna is no longer just a hardware decision, it’s a strategic investment in the future of an airline’s connectivity capabilities,” said Bill Milroy, Chairman and CTO of ThinKom Solutions. “This handbook offers a vendor-neutral, technology-forward perspective that helps airlines, especially those without extensive wireless R&D teams, to make smart, future-ready decisions.”
“Seamless connectivity already is a customer expectation. Worldwide robust coverage requires flexibility and a reliable end-to-end architecture with the right antennas for the right partners,” said Diego Antonio Pozo Morillas, System Design Engineer for LEO Satellite Connectivity at Airbus. “This guide provides further insight into current and upcoming technologies and choices, to get the service right.”
The document also outlines key questions airlines should ask before selecting an IFC system, such as whether it can meet bandwidth demands for full-cabin streaming, whether it’s compatible with emerging multi-orbit networks, and how easily it can be upgraded to support evolving customer expectations.
Produced by Seamless Air Alliance’s expert working groups, comprised of specialists from across the aviation, telecom, and satellite industries, the handbook exemplifies the technical leadership and collaborative rigor that the Seamless Air Alliance brings to the connectivity market.
Releasing this document publicly serves as both a resource and an invitation. It demonstrates the practical value of Seamless Air Alliance membership and encourages airlines, technology vendors, and service providers to consider joining the Alliance. Members gain full access to a deep library of technical documents, implementation guidelines, and future-focused research that supports strategic planning and informed decision-making.
“For suppliers and airlines working to stay ahead of the rapid changes in satellite connectivity, the Seamless Air Alliance offers a front-row seat to the future of inflight connectivity,” said Jack Mandala, CEO of Seamless Air Alliance. “Without access to intelligence like this, organizations risk falling out of sync with where the industry is heading.”
