The Comant CI-157P is a receive-only V-dipole antenna for VOR, localiser and glide-slope navigation signals. It has fixed radiating elements, an integral ferrite balun and a BNC connector.

  • Manufacturer part number: CI-157P
  • Frequency coverage: 108–118 MHz (VOR/LOC) and 329–335 MHz (glide slope)
  • Horizontal polarisation with dipole radiation pattern
  • Nominal impedance: 50 ohms
  • Maximum VSWR: 3.0:1 across both specified frequency ranges
  • Black housing with stainless-steel whips
  • Approximate maximum height: 457 mm
  • Manufacturer-stated maximum weight: 0.23 kg

The CI-157P is designed for Piper aircraft mounting configurations. Its radiating elements are not removable. It is not EASA/FAA approved for helicopter installations. Use the applicable manufacturer installation drawing and approved aircraft maintenance data when determining installation suitability.

Overview

Frequency 108-118 MHz (VOR/LOC) 329-335 MHz (Glide Slope)

"V" dipole VOR/ Glide Slope antenna with fixed elements designed specifically for compatibility with the Piper Aircraft mounting. Integral ferrite balun provides for higher radiation efficiency replacing cumbersome coaxial baluns previously utilized. Radiating elements are not removable.

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.
