Main Product Introduction
The 698-2700MHz Low PIM SISO Omni Ceiling Antenna is engineered for maximum reliability in the most demanding in-building wireless environments. By supporting the critical 700MHz band, it provides excellent signal penetration, making it a favorite for Public Safety (FirstNet) and rural LTE enhancement projects. The omnidirectional dome design provides a seamless 360-degree horizontal coverage area, effectively eliminating dead zones in complex indoor layouts.
This SISO (Single Input Single Output) antenna is built using premium materials to achieve a Low PIM rating of -150dBc. This prevents signal degradation caused by intermodulation, which is a common challenge in DAS systems where multiple frequencies share the same transmission path. Its compact and aesthetically neutral radome allows it to blend into any commercial ceiling, providing a professional finish for RF engineers and architects alike.
Why choose this product?
- Critical Communications Support: Fully optimized for 700MHz and 800MHz public safety and emergency responder radio coverage.
- High Power Capacity: The 50W rating makes it robust enough for use with high-gain BDAs (Bi-Directional Amplifiers) and DAS remote units.
- Consistent RF Performance: Delivers stable gain and Low VSWR across the entire 698-2700MHz range for predictable link budgets.
- Durable & Safe: Manufactured with plenum-rated, flame-retardant materials to meet strict B2B building safety codes.
Application Scenarios
- Public Safety ERRCS: Ensuring code-compliant emergency radio coverage in hospitals, schools, and government buildings.
- Commercial LTE Boosters: Serving as the high-quality indoor service antenna for office cellular boosters and repeaters.
- Enterprise DAS: A reliable workhorse for 4G LTE coverage in warehouses, parking garages, and retail spaces.
- FirstNet Deployments: Specifically tuned for the 700MHz Band 14 required for modern emergency responder networks.

FAQ
- Is this antenna compatible with FirstNet?
- Yes, it covers the 698-806MHz range, making it fully compatible with FirstNet (Band 14) and other 700MHz public safety bands.
- What is the difference between this and a MIMO antenna?
- This is a SISO (Single Input Single Output) antenna with one port. It is more cost-effective for voice-centric or standard data applications. For high-speed 5G data, MIMO antennas are generally preferred.
- Can I use this antenna with a 50W amplifier?
- Absolutely. This antenna is specifically rated for 50W of input power, allowing it to handle signals from high-power DAS remote units without overheating or signal saturation.
- What type of cable should I use with this antenna?
- To maintain the Low PIM performance, we recommend using high-quality 1/2″ super-flexible or RG400 coaxial cables with N-type connectors.
