Product Overview

Southwest Antennas Part # 1055-342 is a right hand circularly polarized (RHCP) directional patch antenna that is designed for SATCOM applications. This product utilizes space-rated components and adhesives making it suitable for use on satellites, manned or unmanned spacecraft, or other aerospace applications in low or no atmosphere environments.

The antenna's directional RHCP radiation pattern and axial ratio below 3 dB offers robust network connections, and allows radios to connect even when not directly facing one another or within clear line-of-site. With an operating frequency range covering 2.4 - 2.5 GHz the design offers excellent performance in the 2.4 GHz ISM band.

Features: 
  • 2,400 - 2,500 MHz
  • Right Hand Circular Polarization (RHCP)
  • 4.5 dBic Directional Radiation Pattern
  • Light Weight
  • Space-Rated Adhesive and Components
  • Brass SMA(f) RF Connector
  • Markets and Applications include:
    • Aerospace
    • Military / Defense
    • Space Research and Earth Sciences
    • SATCOM Systems
    • CubeSats and Nanosatellites
