Hi Hai,
It is not my video: I found it by searching youtube.
Just by visual from video, I think that I saw it could be bought online /ebay/amazon etc.
By searching/reading recent posts/ "cca. last 30 days" from this group, you could find pictures/ links/where to buy maybe even "stronger" directional antennas which could have longer range but keep in mind if you will use such "stronger/more 'dbi's? " antennas that you should protect TinySA with attenuators because such antennas will send more 'dBm's/power to TinySA input.
?
Regards,
Toni
