forumer review: 14dbi panel directional vs 16dbi yagi at 1KM

testing devices:
a) buffalo router as signal transmitter
b) 1000mW usb wifi adapter as signal receiver
c) directional antenna: 14dbi panel DIY stock, 16dbi yagi.



1) Get ready a DIY stock of 14dbi panel directional antenna and 16dbi yagi antenna for PK testing.














2)This buffalo device as signal source.






















3) Signal transmitted from here:





















4) Receiving point at here:



















5) Bird-eye view: range ~ 1.08 KM, not fully open space, partially obstructed by buildings in between, 15 tilt degree。















6) Horizontal view.



















7) Result: very little differences in terms of signal level between 14dbi panel vs 16dbi yagi. As such, tester recommended 14dbi panel for its compact size, easy handling and its dbi/price/performance ratio.
