A low-angle monopole antenna provides coverage from 0 degrees to +40 degrees above the horizon. A separate crossed dipole antenna provides circularly polarized high angle coverage in the +40-degree to 90-degree (zenith) elevation sector. The high angle mode’s hybrid coupler and 50-ohm load termination are housed internally to the unit thereby greatly simplifying installation and reducing customer supplied system accessories to a coaxial switch and interconnecting cables.
Ideally suited for rotary- or fixed-wing aircraft due to its lightweight, low-drag profile and ease of installation, the C175 is also suitable for shelter or shipboard applications. Several versions are available, including the most recent version, the C175-5, which features a strengthened housing for high vibration environments.
