C99 Series Antenna

The C99 Series of antennas present a unique, low-silhouette configuration which produces a very broad beam radiation pattern with minimal gain variation over the entire upper hemisphere. Right-hand circular polarization is maintained throughout the hemisphere.

The C99 Series features other design parameters which complement its deployment. These units are constructed of lightweight materials for ease of handling and mounting, and are provided with lightning protection.

All configurations require the use of a load termination.
