Sometimes, you simply need Bluetooth HIGH Energy📡


@stacksmashing How much gain are you able/have calculated to get from this PCB-Yagi design?
It would also be interesting to know how much the two screws influence it.
@DF3LX I haven't measured it yet - but the directional effect is very very noticable. The antenna is just a random cheap one.
I was frustrated with all nRF-based BLE sniffers that I could find only having not-so-great chip-antennas.
Even with a 2.4GHz stub-antenna this one performs sooo much better
