This Happymodel ExpressLRS (ELRS) Omnidirectional U.FL Antenna is for the EP1 RX 2.4GHz Nano series receiver. The EP1 RX has an open-source program based on ExpressLRS. Due to the low-latency and high-refresh-rate RF module, they are very comfortable for FPV Racing and Long Range FPV. These are very suitable for Tiny whoops because of the ultra-light and Nano size!

Note: This is the antenna only. The EP1_RX is sold separately.
