Main Product Introduction
The 350-960MHz UHF Omni Ceiling Antenna is a mission-critical component for indoor signal enhancement. Specifically engineered to cover the lower RF spectrum, it is the ideal choice for Public Safety DAS systems where reliable communication for emergency responders (Police, Fire, EMS) is mandatory. Its omnidirectional horizontal beamwidth ensures that signals are distributed evenly across the floor, even in signal-dead zones such as basements and stairwells.
Constructed with UV-protected, fire-retardant ABS materials, this antenna is built to withstand the rigors of long-term indoor operation. The low-gain (1.5-2.2dBi) design is intentional, providing a stable, predictable coverage footprint that simplifies the link budget calculation for engineers. Whether used for TETRA, P25, or Industrial IoT, this antenna delivers the consistent 50-ohm impedance matching required for high-reliability wireless networks.
Why choose this product?
- Critical Communications Ready: Fully supports the 380-470MHz and 700/800MHz bands used for global public safety services.
- Uniform 360° Coverage: High-efficiency Omni pattern eliminates signal gaps in large indoor areas.
- Wideband Versatility: One antenna for UHF radio, FirstNet, and legacy GSM900 systems, reducing hardware complexity.
- Reliable N-Type Interface: The N-Female connector provides a secure, threaded connection that minimizes signal leakage and VSWR issues.
Application Scenarios
- Public Safety DAS (ERRCS): Ensuring emergency responder radio coverage in high-rise buildings and underground facilities.
- TETRA & P25 Networks: Ideal for government offices and utility plants requiring secure UHF voice and data.
- Industrial IoT & SCADA: Providing the wireless interface for 900MHz smart sensors and automation in manufacturing plants.
- Signal Boosters & Repeaters: Serving as the service antenna for indoor cellular boosters in areas with weak outdoor signal.

FAQ
- Is this antenna suitable for Public Safety code compliance?
- Yes, it covers the 700/800MHz bands required for NFPA/IFC fire code compliance in Emergency Responder Radio Coverage Systems (ERRCS).
- Can I use this antenna for Wi-Fi?
- No, this antenna is designed for lower frequencies (350-960MHz). For 2.4GHz or 5GHz Wi-Fi, you would need a different antenna model.
- What is the mounting procedure for this ceiling dome?
- It typically mounts through a small hole in a ceiling tile, secured from behind with a plastic nut, ensuring a clean and professional look.
- Does this antenna handle high power?
- While designed primarily as a service antenna for DAS, it can typically handle standard indoor repeater power levels. Please check the specific wattage rating for high-power transmitter use.
