It’ll be useful if you wanna beam your 802.11b signal a few hundred yards or even 1000+ (line of sight), but its hugely *directional* so the receiver best has to be stationary.
Otherwise the average 11b antenna is designed for “broadcast” – wide-beam vs spotlight data transmission.
Looks like a sound conventional design… wish I could tell you more but I fell asleep in “Communications 101” class. blackeye:
