Wi-Tek - WI-ANT19-90 - 90° Sector Antenna

Product Overview

WI-ANT19-90 is a directional antenna for PTP and PTMP wireless links operating across the 5.1-7.125GHz frequency range. It provides 19dBi gain with a 90° horizontal beamwidth and 4° vertical beamwidth, making it suitable for wide-sector outdoor wireless coverage. The antenna features double dual-slant polarization, four N-type connectors, DC-ground lightning protection, and adjustable mechanical tilt.

Key Configuration

Model: WI-ANT19-90 | Frequency Range: 5.1-7.125GHz | Gain: 19dBi | Beamwidth: 90° horizontal, 4° vertical | Polarization: Double dual slant (2V+2H) | Connectivity: 4×N-type connectors | Impedance: 50Ω | VSWR: <2.0 | Mounting: Ø30-70mm pole

Key Features

• · 19dBi directional gain for PTP and PTMP wireless links
• · Wide 90° horizontal beamwidth supports broad sector coverage
• · 4° vertical beamwidth focuses the radio signal in the intended coverage area
• · Operates across the 5.1-7.125GHz frequency range
• · Double dual-slant polarization with 2V+2H configuration
• · Four N-type connectors support multi-polarized radio connections
• · Isolation greater than 25dB and front-to-back ratio greater than 25dB
• · Supports up to 50W maximum power per port
• · Mechanical tilt adjustment from -10° to 3°
• · DC-ground lightning protection and weather-resistant aluminum construction

Technical Context

The 90° horizontal beamwidth provides broad sector coverage, while the narrow 4° vertical beamwidth helps concentrate energy across the intended service area. Double dual-slant polarization supports separate vertical and horizontal signal paths, and the specified isolation and front-to-back ratio help limit unwanted coupling and rear radiation.

Installation Notes

The antenna measures 700 × 250 × 50mm and weighs 4.5kg. It is designed for pole mounting on poles from Ø30mm to Ø70mm, with mechanical tilt adjustment from -10° to 3°. The aluminum antenna uses DC-ground lightning protection and should be connected using suitable 50Ω N-type cabling.
