Overview
The Ubiquiti HORN-5-45 is a 5 GHz horn antenna designed for compatible Ubiquiti radios. It provides a 45° beamwidth in both horizontal and vertical polarization, with 15.5 dBi gain for controlled sector coverage.
RF Performance
The antenna operates from 5.15 to 5.85 GHz and uses dual-linear polarization. Ubiquiti specifies 45° HPOL, 45° VPOL, and 45° elevation beamwidth, with 17 dB cross-polarization isolation and a maximum VSWR of 1.7:1.
Compatibility
The HORN-5-45 is compatible with Ubiquiti IsoStation IS-M5, IsoStation IS-5AC, PrismStation PS-5AC, and airFiber AF-LTU radios. The horn antenna is designed as a replaceable antenna component for these compatible radio platforms.
Key Features
- 5.15–5.85 GHz operating frequency range
- 15.5 dBi antenna gain
- 45° HPOL, VPOL, and elevation beamwidth
- Dual-linear polarization with 17 dB cross-polarization isolation
- 200 km/h (125 mph) wind survivability
Applications
- 5 GHz point-to-multipoint wireless networks
- Sector coverage using compatible Ubiquiti radios
- PrismStation and IsoStation wireless deployments
- airFiber LTU radio deployments
DC Supplies Product Note
The HORN-5-45 is an antenna component rather than a complete wireless radio. Verify the exact compatible radio model before ordering, as Ubiquiti specifies compatibility with selected IsoStation, PrismStation, and airFiber AF-LTU platforms.
