you can, but the beamforming aspect doesn't 'narrow' the broadcast in any meaningful way- the term has more to do with tuning the signal (in software) to an arbitrary location in space than its name might imply (not at all like laser beams) each individual antenna radiates whatever 'shape' of signal based on its physical design, and beamforming is what we call it when multiple antennas reaching the same general area micromanage the phase of each broadcast so as to constructively interfere at a specific target in that area (at the expense of a generally muddier signal elsewhere) so beamforming is cool because it can give you a few dB of extra signal entirely in software, but a proper directional (high-gain) antenna will get you tens of dB, the downside is that it must be physically aimed as far as i understand the state of the art: if you want a 'narrower' signal, you pretty much need to use a 'more directional' physical antenna design
