Sinclair’s high-performance UHF in-building antennas

ResourcesRequest Info

Sinclair’s high-performance UHF in-building antennas are low profile and ground plane independent, featuring an inconspicuous design that blends into any environment. Their high efficiency, low-PIM rating, and wideband characteristics ensure optimal performance. These antennas feature LSZH (low-smoke and halogen-free) cables which are plenum rated and a fire retardant radome rated at UL94-V0, to comply with the most stringent in-building fire regulations globally.

 

SI300-O Series (380–512 MHz)

  • Features: Low-profile, ground-plane independent, NFPA-compliant, IP66-rated, low PIM.
  • Applications: Public safety and mission-critical indoor coverage.

SI400-O Series (694–6000 MHz)

  • Features: Wideband, compact design, NFPA-compliant, IP66, low PIM.
  • Applications: LTE, 5G, Wi-Fi, CBRS, and multi-band DAS systems.

SI240F-O Series (132–960 MHz)

  • Features: Ultra-low-profile, multi-band (VHF/UHF/700/800/900 MHz), NFPA-compliant, low PIM.
  • Applications: First responder and public safety networks indoors.

SI500 Series (617–8500 MHz)

  • Features: Ultra-wideband, ceiling-mount, MIMO support, NFPA-compliant, low PIM.
  • Applications: 5G, Wi-Fi 6E/7, IoT, and high-density indoor environments.
These antennas are primarily used within Distributed Antenna Systems (DAS) to enhance coverage in large or challenging indoor spaces—including commercial buildings, stadiums, transportation hubs, and mission-critical public safety venues.
