Overview

Frequency • 108-118 MHz (VOR/LOC)
329-335 MHz (GS)


“V” Dipole VOR/LOC/GS antenna with detachable elements mounts on top of the vertical fin stabilizer offering the four-hole mounting configuration found on many beech aircraft. RF design similar to the CI 157P. Integral ferrite balun provides for higher radiation efficiency. Detachable elements result in a significantly smaller shipping and storage carton than fixed element versions.

Note: Comant Antennas no longer come with a gasket or a template. Must order PN 09-05579 separately.

Not approved for helicopter installations.

Applications
Single engine piston aircraft for applications of this antenna design. Consult your FBO or installation shop for best application information.
