Product Description

Product Description

The GL1727-21D32EAG4B is a four-port narrow beam panel antenna operating across the 1710–2690 MHz frequency range. It supports dual ±45° polarization and is designed to deliver stable high gain from 18.9 to 20.5 dBi with low VSWR (≤1.5). The antenna provides a horizontal beamwidth of 32° and a vertical beamwidth of 8°, along with strong sidelobe suppression and a front-to-back ratio of at least 25 dB. Each port handles up to 300 W input power and uses 4.3-10 female connectors. The FRP radome, DC grounding lightning protection, pole-mount installation, and adjustable mechanical tilt from 0–10° make it suitable for outdoor cellular network deployments.
