I bought some cheap aliexpress directional 2.4GHz antennas.
As expected, they aren't very good.
(A small thread)
Using a tool borrowed from
@jilles_com
, I can see that this antenna is sensitive to various frequencies but not much at ~2.4GHz.
This antenna is best at around 1070MHz or 337MHz and has some sensitivity to 1090MHz meaning it works somewhat okay for ADSB aircraft tracking.
