Just because there is space that accommodates the mounting doesn’t mean it’s the right space. According to the manual, the antenna should be well removed from all projections, engines, and propellers, of course. So does Avidyne.įor instance, the install manual for the Garmin GTR200 VHF com radio is pretty specific about locating the com antenna. Garmin is one that gets it right, specifically offering detailed guidance in its equipment installation manuals for installing antennas. Most avionics manufacturers do a good job of spelling this out in their installation manuals while also offering valuable guidance on building a ground plane on non-metal surfaces.
The current avionics install data should be the final say as to where you mount antennas and how you terminate connectors and route the coaxial cabling, but you’ll likely make some compromises. That’s a Comant CI 2580 combo pictured here. It can do the job of two antennas in one, saving installation effort.
