Designed for the evolving 5G landscape, these high-performance ceiling antennas handle the broad spectrum required for mid-band cellular deployment, providing seamless indoor coverage for high-density environments like offices, malls, and transit hubs. Unlike standard external antennas, these low-profile solutions are used at central distribution points within Distributed Antenna Systems (DAS) to ensure the cleanest possible signal environment with a uniform 360° omnidirectional pattern. Key features include a wide frequency range supporting 698-3800 MHz (covering sub-6GHz 5G, LTE, and Wi-Fi 6 bands), a low VSWR of ≤ 1.5:1, and a compact, aesthetically pleasing design that mounts flush to various ceiling types. Engineered for carrier-grade performance, they feature an ultra-low PIM rating of ≤ -153 dBc to -160 dBc to prevent noise floor elevation and maintain high data throughput in sensitive receiver environments. Built with flame-retardant plenum-rated radomes and high-quality mechanical interfaces such as N-Type or 4.3-10 connectors, these rugged antennas provide a secure, low-loss solution for permanent 5G indoor installations requiring superior signal integrity and high-power thermal management.
