Directional wifi antennas

(1/4) > >>

Jason Lavoie:
Has anyone tried directional antennas for wifi control systems?
like this http://www.tp-link.com/en/products/details/cat-5063_TL-ANT2424B.html
or maybe less directional depending on the coverage pattern you need

it seems like most of the time when you need more range you know what direction you'll be heading and could aim the antenna before you head out

Also wondering if I'd need to replace all of the antennas on the router, or just one? (is each antenna for a different band, or is it diversity like a wireless mic?)
diversity doesn't seem likely since a lot of routers have an odd number of antennas so I'm not sure.

It can be a bit of a crap shoot trying to replace one of those little whip antennas on a consumer wifi box.

That being said, I like this antenna a lot:

The Pringles wifi antenna worked well for me and is very directional.  Here is a commercial version:

I'd put them on all and separate them by a foot or so

I bought a Ubiquiti Nanostation M5 and can go about a 1/4 mile before I see the signal start to drop. Its a WAP instead of an antenna, but it is directional.

With the cantenna on both ends it can go a couple of miles.  On 1 end a mile.
