Gilat Satellite Networks continues its growth momentum, significantly expanding its order backlog with a $60 million deal to supply electronic antennas for in-flight connectivity. The Israeli communications company, led by CEO Adi Zefadia, has secured a major order from a leading global satellite operator for its ESA (Electronically Steered Antenna) Stellar Blu Sidewinder terminals.
The Sidewinder antenna, designed to deliver high-speed satellite-based Internet connectivity to civil and executive aircraft, will now be integrated directly into aircraft during production — a process known as Linefit installation. The antennas will be installed at Boeing’s manufacturing facilities, streamlining the supply chain and reducing installation costs compared to the traditional post-delivery installation at airline sites.
This transition to Linefit is expected to significantly enhance Gilat’s profitability, as it enables the company to charge premium prices due to the stricter compliance standards required by aircraft manufacturers.
Following the announcement, Gilat’s shares jumped 4.7% at the opening of trading on Wall Street.
Shift to Linefit Installations Marks Strategic Milestone
The $60 million order follows the satellite operator’s recent success in securing new airline agreements. These contracts are driving demand for hundreds of Sidewinder terminals, which will now be delivered over the next 12 months.
Gilat anticipates a full transition to Linefit installations by 2025, with more than 50% of installations expected to occur at aircraft manufacturers’ sites — including Boeing — by 2027.
Sidewinder: A Key Asset in the LEO Satellite Era
The Sidewinder antenna was originally developed by U.S.-based Stellar Blu and acquired by Gilat in January 2025 for $98 million, with an additional performance-based consideration of up to $147 million. The technology is designed to meet the demands of modern satellite communication networks, particularly the growing trend of Low Earth Orbit (LEO) constellations.
Unlike mechanical antennas, Sidewinder's electronically steered technology enables fast, seamless handovers between satellites — a critical capability as some LEO satellites require connection switches every 10 minutes. The antenna is also more reliable and cost-effective than mechanical alternatives.
With this latest order and its growing integration into aircraft production lines, Gilat is positioning itself as a major player in the future of in-flight connectivity.
