Desktop Antenna, SMA Plug, 2.4–2.5 GHz, 5.5 dBi – UL-103

Product Description

Desktop Antenna, SMA Plug, 2.4–2.5 GHz, 5.5 dBi – UL-103

Part Number: UL-103

The UL-103 is a compact desktop antenna for the 2.4–2.5 GHz band (2.45 GHz Wi-Fi/ISM). It connects via a standard SMA plug (conventional male) to 50 Ω radios, routers and adapters, providing around 5.5 dBi of omnidirectional gain to improve local coverage without wall or mast mounting.

• Band: 2.4–2.5 GHz (802.11b/g/n, Bluetooth®, 2.4 GHz ISM)
• Connector: SMA plug (male)
• Impedance: 50 Ω
• Gain: approx. 5.5 dBi (omnidirectional)
• Form factor: desktop antenna for quick, tidy placement

Good use-cases

• Improving 2.4 GHz Wi-Fi coverage on a desk or shelf without drilling
• Routers, adapters and IoT gateways that accept an external SMA antenna
• Bench/test setups needing a consistent on-desk 2.4 GHz radiator

Install tips

• Place the antenna upright and in the clear (away from large metal objects).
• Use a short, low-loss 50 Ω pigtail if you need extra reach; keep total cable length modest at 2.4 GHz.

Compatibility – quick check
Use this antenna if your device has a 50 Ω SMA jack (female) and operates in the 2.4–2.5 GHz band. For RP-SMA, N-type, TNC or TS-9 ports, add an appropriate adapter/pigtail.

Note: If your original listing showed “2.4–2.5 MHz”, that’s a typo – this product is a GHz-band antenna.
