Omni Antennas

High Performance Broadband
Microwave Antennas

Southwest Antennas offers a variety of Omni antennas in bands from 0.35 to 8. 5 GHz. An Omni antenna radiates 360° in the horizontal plane. Peak gain is usually on the horizon. All collinear Omni antennas are centre-fed making them grund plane independent and providing stable radiation patterns across the band.

SWA Omni Antennas:

Types of Mounts

Four types of mounts are used to support almost all of our omni antennas. 

1. Standard Connector Mount: This light yet sturdy antenna is mounted directly by several connector options, allowing for a variety of applications. Most connectors are type N or TNC, male or female.
2. Flange Mount: A flanged mounting base makes an antenna ideal for many ground-based and airborne applications.
3. Microwave Mag-Mounts: A strong moveable magnetic base for various vehicle uses.
4. STC Mount: A mount designed especially for airborne applications.

 Antennas with springs: A strong steel spring that supports the antenna above the base is available for mounting options. The springs can be bent horizontally and spring back into vertical position, making them ideal for mobile uses such as camara-back transmitters or handheld receivers.

Need a different mount or connector?  We can make changes as per your mount, connector, and spring requirements in most cases.  

ROHS compliant: SWA produces ROHS compliant antennas when required.

Heavy duty spring bases: Available on most omni antennas upon request.

New Internal LNAs!! Available on C band omni antennas as per client specification (see Sleeve Dipole Omnis: 1088-003 & 1088-007)
