Sinclair Technologies Donor Antennas

Sinclair Corner‑Reflector & Yagi Antennas

Corner‑Reflector Donor Antennas

  • Features:
    • Directional design with gains from 7 to 12 dBd
    • Heavy-duty construction, suitable for severe weather and ice loading
    • VSWR ≤ 2:1, DC-grounded, N‑male connector
    • Optional stacked arrays (dual/quad) for higher gain
  • Applications:
    Ideal for focused outdoor signal reception in mission-critical systems (public safety, LMR/PMR), ensuring strong uplink uplink and minimized feeder loss

Yagi Donor Antennas

  • Features:
    • Directional broadband design with ~10 dBd gain (some models up to 15.5 dBd)
    • Options include rugged, low‑PIM, radome-enclosed variants; some feature heated elements for cold climates
  • Applications:
    Perfect for focused coverage and supporting uplink reliability in DAS and TTA installations for LMR and cellular networks

These donor antennas act as outdoor “donor” elements, capturing external signals and feeding them into the DAS’s amplifier system, enhancing both uplink and downlink performance in large or signal-challenged environments.
