Need Wifi Antenna which is Powerful and Cheap

Hello. I would like to buy a wifi antenna with the greatest signal
strength for the lowest cost. I found some 24 dbi for 50 dollars. If
you know of a better deal, please let me know. Thanks in advance.

to be used where, how, as AP or Client ?
directional or omni ? what are you aiming at ?
how far is the electronics - ie, cable length ?
inside or outside ?
mounting issues ?
path issues - trees, buildings, etc ?

An antenna can not be 'powerful', nor can a speaker.

Based upon the lack of specifics in my original question, I decided to
revise it.

I would like to buy a wifi directional antenna for my computer's nic
card. It should have a high gain for a low cost. I would prefer an
indoor antenna but an outdoor is fine. The connector is a SMA and the
cord only needs to be a few feet. I found some 24 dbi for 50
dollars. If you know of a better deal, please let me know. Thanks in
advance.

Hi. That helps, but it's best if you give an indication of the
situation that you intend to use it for.

All too often somebody looking for the highest gain, has no clue as to
how much gain they actually need and are trying to buy a laser when
what they really need is a flashlight.

Is the AP (presumed) you are connecting to far away? Do you
understand the tradeoffs of using something as precise as a 24 dbi
antenna? How hard it will be to aim for closer sources? That the
mount should be well fixed ?

Unless the post begins with - I'm doing a 1(or more) kilometer link
and ......- I think that high of gain would not be appropriate for
most circumstances that an amateur would find themselves in. More
likely you want a 10-14 dbi panel or backfire antenna.

Cheers,
Steve

.... where those dollars are real but the dBi's probably pure fantasy. Care
to point to a site promoting this work-of-the-devil to give us all a laugh?

Correction: it has to be directional for any gain whatever over 0dBi.

[Where on earth could antenna gain come from except from directionality?]

The distance is from my house to my brother's house which is one
block away.

Yes. I would have to aim it at his house with about a 8 degrees
margin of error. That should not be much of a problem.

>*That the mount should be well fixed ?

I was hoping to get an antenna that could be used on a small
portable mount on my patio or inside the house.

Actually, I am currently using an Airlink 10 dBi antenna, but my
connection speed is between 2 and 5.5 Mbps rather than 54 Mbps. It is
a weak signal.

Okay, I can believe that one. Looks like an outdoor antenna. You'll need
to mount the electronics real close or lose much of your antenna gain in
cable losses. I hope you understand the significance of the 8 degree
beamwidth - it means it's much like a focused flashlight where you get to
choose what you illuminate but with no performance in any other direction.
