Antenna 4031 2L 2M 1.6m
Compact trio net power for space constrained sites
Antenna 4031 is a compact trio net passive antenna that brings wide low band and mid band support, high RF efficiency and built in telemetry into a small 1.6 m by 399 mm form factor. At around 25.5 kg including mounting, it is ideal for rooftop and constrained sites where every centimeter and kilogram matters, without compromising coverage, capacity or upgrade flexibility.
Small size, big performance
Antenna 4031 fits tight rooftops while delivering up to 90% efficiency and outstanding coverage.
Peak RF performance
Delivers 698–2690 MHz coverage, best-in-class PIM, and flexible setups for high capacity and robustness.
Smart and sustainable
Built-in monitoring enables faster ops, while a lightweight recyclable design cuts site load and TCO.
AI-ready radios, antennas, and RAN software powering future networks
Ericsson has introduced a new AI-first RAN portfolio combining AI-ready radios, trio net antennas, and AI-powered RAN software to boost uplink performance, energy efficiency, and service differentiation for 5G and beyond.
