Indoor Omnidirectional Ceiling Antenna for 2G/3G/4G/5G DAS Systems
In the rapidly evolving landscape of wireless communications, indoor signal coverage is paramount. Our latest series of indoor omnidirectional ceiling antennas is engineered to meet the demanding requirements of modern multi-system networks. Covering mainstream communication frequency bands from 698 to 3800 MHz, and up to 2700 MHz in select models, this antenna series ensures reliable and stable performance for 2G, 3G, 4G, and 5G deployments. Its compact design and easy installation make it an ideal choice for indoor DAS (Distributed Antenna Systems) in offices, shopping malls, hotels, and public venues.
indoor omni ceiling antenna: Broadband Frequency Performance
One of the standout features of this indoor omni ceiling antenna series is its exceptional broadband frequency coverage. Models MOP-OCA-738-3/6NF(MF/DF) and MOP-OCA-727-2/5NF(MF/DF) are tailored to support a wide range of bands. The MOP-OCA-738 variant operates from 698 to 960 MHz and 1710 to 3800 MHz, while the MOP-OCA-727 covers 698 to 960 MHz and 1710 to 2700 MHz. This versatility ensures compatibility with legacy 2G and 3G systems, as well as modern 4G LTE and 5G NR networks. The antenna’s vertical polarization and 360° horizontal omnidirectional radiation pattern provide uniform coverage, eliminating dead zones and ensuring seamless connectivity.
Key Electrical Specifications
To achieve stable and low-interference signal transmission, this indoor omni ceiling antenna delivers reliable electrical performance. With a voltage standing wave ratio (VSWR) of ≤1.8 and third-order passive intermodulation (PIM) of ≤-150 dBc at 2×20W, the antenna minimizes signal reflection and distortion. The maximum input power is 50W, and the characteristic impedance is 50 ohms, ensuring compatibility with standard feeder systems. The following table details the electrical and mechanical specifications for both models.
