Overview
The Ubiquiti HORN-5-90 is a 5 GHz horn antenna with 90° horizontal and vertical beamwidth, designed for sectorized wireless deployments using compatible Ubiquiti radios. Its asymmetrical horn design provides controlled radiation characteristics for installations where beam shaping and co-location performance are important.
RF Performance
The HORN-5-90 operates across 5.15–5.85 GHz and provides 13 dBi gain. It uses dual-linear polarization with 90° HPOL and VPOL beamwidth and a 45° elevation beamwidth. Maximum VSWR is 2:1, while cross-polarization isolation is specified at 17 dB.
Radio Compatibility
The antenna is compatible with Ubiquiti IsoStation IS-M5, IsoStation IS-5AC, PrismStation PS-5AC, and airFiber AF-LTU radios. It uses the modular horn antenna interface for compatible radio installations.
Co-Location and Sector Deployment
The HORN-5-90 is an asymmetrical horn antenna designed with naturally attenuated side lobes and low back radiation. This beam-shaping approach is intended for sector cluster deployments where controlled coverage and radio co-location are important design considerations.
Key Features
- 90° horizontal and vertical beamwidth
- 13 dBi antenna gain across 5.15–5.85 GHz
- Dual-linear polarization with 17 dB cross-polarization isolation
- 45° elevation beamwidth and 2:1 maximum VSWR
- Compatible with selected Ubiquiti IsoStation, PrismStation, and airFiber LTU radios
Applications
- 5 GHz sectorized wireless networks
- WISP access infrastructure
- Clustered sector deployments
- Wireless networks requiring controlled beam shaping
- Outdoor fixed wireless infrastructure
DC Supplies Product Note
The HORN-5-90 is a modular antenna rather than a complete wireless radio. Verify that the selected Ubiquiti radio uses the compatible horn antenna interface before deployment, and account for the antenna's 90° coverage pattern when planning sector layouts.
