Ultra-low loss RF adaptor suitable for frequencies up to 6GHz. U.FL connectors are commonly seen on PCBs, such as single-board computers used for Meshtastic.
Please note an N male connector is shown in the photo - the shipped product will have N female.
Ensure appropriate strain relief is present as the U.FL connector is fragile. Neither U.FL nor N connectors are waterproof, so connections outdoors must be taped with self-amalgamating tape.
