Omni Antenna, 1.7–1.9 GHz, 9.5 dBi – SPDD120

Product Description

Omni Antenna, 1.7–1.9 GHz, 9.5 dBi – SPDD120

Part Number: SPDD120

SPDD120 is a vertical omnidirectional antenna covering 1.7–1.9 GHz (common LTE Band 3 / DCS/PCS ranges). With approx. 9.5 dBi gain it provides a stronger, cleaner all-round signal than compact on-device whips, ideal for outdoor installs where clients or base stations are spread around the site.

• Frequency band: 1.7–1.9 GHz (LTE Band 3 / PCS region)
• Gain: approx. 9.5 dBi (vertical omni)
• Impedance: 50 Ω
• Polarisation: vertical
• Connector: base RF connector (typically N-type; match with a short pigtail to your device)
• Outdoor-ready fibreglass/metal construction for pole/wall mounting

Good use-cases

• Expanding outdoor coverage around buildings, yards and campuses at ~1.8 GHz
• 4G/LTE routers or small cells where users are distributed in all directions
• Industrial/telemetry systems operating within 1.7–1.9 GHz

Install tips

• Mount upright and as high/clear as practical for best 360° coverage.
• Use low-loss 50 Ω coax (e.g. 200/240/400-series) and keep runs short.
• If using two for diversity/MIMO, separate by distance and mount parallel.

Compatibility – quick check
Works with 50 Ω radios/APs operating in 1.7–1.9 GHz. If your device uses SMA, RP-SMA, TNC or other connectors, add the appropriate short pigtail from the antenna’s base connector to your RF port.
