coaxial antenna

[kō′ak·sē·əl an′ten·ə]
(electromagnetism)
An antenna consisting of a quarter-wave extension of the inner conductor of a coaxial line and a radiating sleeve that is in effect formed by folding back the outer conductor of the coaxial line for a length of approximately a quarter wavelength.

This requires removal (or at least partiallremoval) of the aircraft headliner or overhead panels, cutting a hole, mounting the antenna, sealing the antenna, running coaxial antenna cable from the GPS antenna to the GDL82 and then putting it back together.

For the next coaxial antenna (antenna 2), a small gap in the outer conductor, spaced a quarter-wavelength back from the end of the coaxial line, is added to the simple extended inner conductor antenna.

In fact, if you battle performance issues with an existing navcomm, it might make sense to replace antennas first (after bench test) which might also include coaxial antenna cabling.
Is the navcomm dead? Not quite yet: not everyone needs or can afford a new color mapcomm, so there's still a place for venerable navcomms as second fiddle. Here's how to buy smart
