Founded in 1974 at Sebastian Airport by Frank Campbell and Bob Sellers, Sebastian Communication, Inc. has grown into a leading FAA-Approved Avionics Repair Station, now operating from a 5,000-square-foot hangar at Merritt Island Airport.

We specialize in avionics sales, installation, and repair for a wide range of piston aircraft, including Cessna, Cirrus, Piper, Beechcraft, Mooney, Tecnam, and Diamond Aircraft. Our team works with top avionics brands such as Garmin, Aspen, L3Harris, Avidyne, and Genesys/S-TEC, providing expert service for autopilots, EFIS, MFDs, GPS/NAV/COM systems, and more.

In addition to avionics upgrades, we design and fabricate custom instrument panels using advanced in-house CAD and CNC tools. For experimental and light sport aircraft, we offer fully tailored avionics and panel kits — available as plug-and-play systems or complete installations with precision wiring built to fit your aircraft perfectly.
