Directional Antennas & Beamforming

Discussions focus on the use of directional antennas, phased arrays, yagi, parabolic dishes, and beamforming techniques for focused wireless signal transmission, reception, jamming, or countermeasures, debating feasibility, size, cost, and effectiveness.

no it's not, you use a directional antenna or phased arrays and beamforming (which is what they're doing).

Only if this is cheaper, and you have room for a big antenna.

Could this also be used for a giant antena?

physical intrusion? lame.. get a parabolic or yagi antenna

Feels like a bug. Any technical reason why this wouldn't be doable with all antennas firing?

gallamine Feb 19, 2014 View on HN

Perhaps the "trick" is a large number of antennas to produce an ultafine beam pattern?

c_o_n_v_e_x May 13, 2024 View on HN

Some articles reference they are using a phased array antenna

PretzelFisch Oct 15, 2015 View on HN

you might want to look into a yagi antenna design.

No it's radio waves with directional antennas

Can't you just jam it with a very directional antenna?
