Sector Antenna, N Jack, 2.4–2.5 GHz, 5 dBi – UL-122-01 (UniLink)

Product Description

Sector Antenna, N Jack, 2.4–2.5 GHz, 5 dBi – UL-122-01 (UniLink)

Part Number: UL-122-01

The UL-122-01 is a UniLink sector antenna for the 2.4–2.5 GHz band, fitted with a standard N jack (conventional female) connector and designed for 50 Ω Wi-Fi / ISM systems. It provides around 5 dBi of gain with a wide horizontal beam, giving more focused coverage than a simple omni but without the very narrow beam of a parabolic or high-gain panel. :contentReference[oaicite:1]{index=1}

Typical applications

• 2.4 GHz Wi-Fi access points needing sector coverage instead of full 360°
• Covering a yard, car park, courtyard or one side of a building
• Short- to medium-range point-to-multipoint links at 2.4 GHz
• Industrial / telemetry systems in the 2.4 GHz ISM band

Installation tips

• Mount vertically on a pole or sturdy bracket, with the panel facing the area you want to cover.
• Use low-loss 50 Ω coax (e.g. 200/240/400-series) and keep the cable run as short as practical.
• Set your access point polarisation (usually vertical) to match the antenna orientation.

Compatibility – quick check
Use this antenna if:

• Your radio or AP operates in the 2.4–2.5 GHz band, and
• You can connect to an N jack (female) on the antenna (often via a short N-plug to RP-SMA/SMA/TNC pigtail).

For devices with SMA, RP-SMA or other connector types, simply use an appropriate pigtail from the N jack on the antenna to your equipment’s RF port.
