This antenna collar is designed for the Elecrow ThinkNode M1 and ThinkNode M5. It reinforces the RP-SMA Gizont antenna connection, reducing stress on the RP-SMA connector, and provides an easy way to color-code radios for fast visual identification in the field. When used with an RP-SMA male Gizont antenna, the adapter redirects lateral loads away from the RP-SMA connector and into the radio body. This results in a more stable antenna, improved long-term durability, and a significantly lower risk of connector damage from bumps, drops, or handling. Key benefits Protects the RP-SMA connector from lateral stress Improves antenna rigidity and overall durability Ensures load is applied perpendicular to the connector, where it is strongest Enables color-coding for quick device identification Compatibility Elecrow ThinkNode M1 Elecrow ThinkNode M5 RP-SMA male Gizont antenna
