OMNI-A0142

OMNI-A0142 High Gain S-Band Omni

2.0 – 2.5 GHz
Alaris Antennas


The OMNI-A0142 is a wideband, high-gain S-band omni antenna for use in the 2.0 to 2.5 GHz frequency range at high-power levels up to 20 W.

The OMNI-A0142 utilises a specially designed wideband collinear dipole array radiator with integrated balun, making it groundplane independent and suitable for use on any mounting platform, such as manpacks and mobile electronic devices, and providing higher gain than many competing antennas across the high frequency range in which it operates.

The radiator is mounted in the top half of the radome to mitigate radhaz. The antenna is designed and intended for use in communications applications in extreme operational conditions.

The OMNI-A0142 is a wideband, high gain omni-directional antenna for use in the 2.0 to 2.5 GHz frequency range at high-power levels up to 20 W.

The OMNI-A0142 utilises a specially designed wideband collinear dipole array radiator with integrated balun, making it groundplane independent and suitable for use on any mounting platform, such as manpacks and mobile electronic devices, and providing higher gain than many competing antennas across the high frequency range in which it operates.

The radiator is mounted in the top half of the radome to mitigate radhaz. The antenna is designed and intended for use in extreme operational conditions.
  • Collinear design gives better gain than dipole and monopole antennas
  • Low VSWR across the band
  • Rugged and lightweight
  • Wi-fi and data communications
