Product Introduction
  1. ROOMTOP 1.0 features a copper outer conductor, offering excellent transmission performance, suitable for scenarios with high signal quality requirements.

ROOMTOP 2.0 uses an aluminum outer conductor, providing good performance at a lower cost, ideal for large-area coverage scenarios with relatively lower signal quality demands.

  1. Application Scope: Leaky coaxial cables are suitable for wireless communication scenarios below 6GHz, particularly for strip-shaped indoor areas such as office buildings, dormitories, corridors, and open spaces like underground parking lots. As a carrier for wireless signal transmission and radiation, they achieve uniform signal coverage, meeting the signal demands of 4G/5G mobile communications, emergency communications, and other scenarios.
  2. Product Advantages:

Uniform Signal Coverage: Signals radiate evenly along the cable length, addressing signal dead zones in narrow and elongated areas, with coverage stability superior to conventional antennas.

Convenient Installation and Maintenance: The integrated cable structure eliminates the need for additional antenna brackets, allowing direct installation along walls, cable trays, etc. Troubleshooting is straightforward, improving maintenance efficiency.

Wide Bandwidth Compatibility: Supports full-band signal transmission below 6GHz, compatible with 4G, 5G, and future next-generation mobile communication technologies, reducing the need for frequent cable replacements and lowering long-term usage costs.
