RadioMaster Dual Band 2.4GHz/Sub-G 900MHz RP-SMA T Antenna 3dBi Omnidirectional for ELRS Modules

Overview

The RadioMaster Dual Band 2.4GHz / Sub-G 900MHz T Antenna is an RP-SMA dual-band antenna designed to simplify dual-band transmitter or radio controller setups by supporting both 2.4GHz and Sub-G 900MHz without swapping antennas. It is an omnidirectional antenna (3DBI class) described as ideal for short to medium-range use, and is shown as a match for the RadioMaster Nomad Gemini Xrossband Module.
