Decided to route the antenna leads across the floor of the cabin. There are three leads on each side of the cabin. The marker beacon, Com 2, and Nav 2 antennas are run across the pilot floor. The Garmin GPS, Com 1, and Nav 1 antenna leads are run across the copilot floor. The leads are run through holes in the center spar section and out to the wings or the com antennas under the cabin. The leads are secured to the floor using tape and plastic tie wraps. They are secured to bulkheads through holes with plastic bushings installed.
