Main Product Introduction
The 400MHz UHF Omnidirectional Ceiling Antenna is a cornerstone component for Emergency Responder Radio Coverage Systems (ERRCS). In modern construction, thick concrete and low-E glass often block external UHF signals; this antenna solves that challenge by distributing high-quality radio signals internally. Its 360-degree horizontal beamwidth ensures that police, fire, and medical personnel maintain crystal-clear voice communication regardless of their location on the floor.
Built for long-term B2B infrastructure reliability, the antenna utilizes high-grade internal copper elements to ensure low VSWR and maximum radiation efficiency. The white, UV-stabilized ABS radome is not only aesthetically pleasing but also meets strict building fire codes. With an integrated N-Female pigtail, it offers a secure, industry-standard connection to 50-ohm coaxial distribution networks, providing a robust link for TETRA and digital radio standards.

FAQ (Frequently Asked Questions)
- Is this antenna compatible with TETRA or P25 systems?
- Yes, it is specifically tuned to cover the 380-470MHz range, which includes the standard operating frequencies for both TETRA and P25 digital radio networks.
- Can this antenna handle the high power of a BDA?
- Absolutely. It is rated for 50W continuous input power, which is more than sufficient for the high-output ports found on industrial-grade Bi-Directional Amplifiers.
- How is the antenna installed in the ceiling?
- The antenna features a threaded mounting bolt on the rear. You simply drill a hole in the ceiling tile, pass the cable through, and secure the antenna with the included plastic mounting nut for a flush finish.
- Does this antenna support 700/800MHz Public Safety bands?
- No, this model is optimized for UHF (400MHz). For 700/800MHz or FirstNet applications, please refer to our 698-2700MHz wideband antenna series.
