RadioMaster Dual-Band 2.4GHz / 900MHz Antenna (2 Pack)

This dual-band 2.4GHz / 900MHz antenna pair suits ExpressLRS transmitter and receiver hardware that runs both bands together, giving a low-latency 2.4GHz link and a long-range 900MHz link from one antenna feed instead of two separate aerials.

Key features

• Covers 2.4GHz and 900MHz at once from a single omnidirectional antenna, so dual-band ExpressLRS gear doesn't need separate 2.4GHz and 900MHz aerials.
• RP-SMA connector on an 80mm coaxial pigtail, 100mm overall length, for flush or offset mounting.
• Peak gain of 3.83dB at 2.4GHz and 3.58dB at 900MHz, with a low SWR of around 1.25-1.27 on both bands.
• Suits dual-band ExpressLRS modules such as the Nomad Gemini Xrossband, and separate ExpressLRS modules like the Ranger (2.4GHz) and Bandit (900MHz) families.
• Sold as a matched pair, ready to populate a diversity antenna setup or fit two separate radios.

Specifications

• Frequency: 2.4GHz and 900MHz
• Connector: RP-SMA
