My telescope shows a dimmer imaqge from a non point source like a nebula
when I increase its magnification. Ultimately a lower f number optical
system is required to increase brightness.
If I want to increase the signal for Wifi, a higher gain narrow band
antenna is suggested by the "expperts"
My geography means that I have no radio Wifi point source signal, but
scattered signals.
More gain is required for a reliable Wifi performance here and surely even
panel or Yagi antennas where sperate antennas are summed have reduced
angular bandwidth and see less scattered signal .
The solution would seem to be multiple receivers and antennas summed, a
costly solution.
I believe complex modulation systems are used to improve but surely this
does not overcome the problem.
Any suggestions

Legit local wifi net all paid for but no line of sight, diffused reflected
source means that a narrower angle higher gain antenna would seem to give a
smaller signal.
