    I live on the 12th floor of a very concrete building. The pool is 12 floors below and 25 meters to the left, of my window.

    The building is thick concrete... to the point that I get NO reception of any TV channels on antennae, because my window faces the opposite direction of every TV tower in the city.

    I want wifi from the pool. I have a D-Link DIR-655. It has 3 antennas, with BNC connectors. I am looking here: http://www.hyperlinktech.com/web/antennas_2400_in.php

    What should I get? Are the standard 'range boosters' much better than the stock antennas?

    I'm not sure I understand the difference between the extenders and the "patch" antennas. :hs:

    those are "omni" antenna. And they suck. For you, I would recommend a Yagi antenna aimed towards the pool. Instread of trying to get the signal to go in a big circle (omni) it will direct it in a very sharp elipse in the direction you aim the antenna. The beam is approximately 20-40 degrees. Perfect for your situation.

    Get a Cantenna, glue it to your outside windowsill, and aim it at the pool. Problem solved.

    EDIT: ...which...is pretty much exactly what Jolly said.

    Yeah but... those directional pads are only $20. And I don't have to assemble a cantanna. Can't I just aim one of those at the pool, from my ceiling?

    Provided that your windows don't have metal-oxides on them to provide tint, anti-glare, and/or UV/IR filtering, yes you could aim an antenna out your window from inside. If they are coated, or if you have a metal screen, the signal will be greatly diminished.

    There is some kind of tint, but I don't think it will matter. There is no screen.

    a Yagi would be perfect, imo. It's an elipical pattern. So where it will direct signal 12 floors down to the pool. it will also radiate outwards to cover several units, and probably a floor or two above you, as well.

    Also, I recommend using either a dedicated AP for the pool to supplement a standard omni AP, or use an AP with multiple antennas that will actually utilize it's multiple antennas (such as the Linksys WRT54Gv4 w/DD::WRT). Using that setup, you can have the one AP with both an omni and yagi antenna for the best-of-both-worlds.

    that antenna you linked would be HORRIBLE.

    It's tuned for 890-960MHz. You need something tuned for 2400-2500MHz.

    well you can get yagis for around $40 without the weatherproof enclosure. But you get what you pay for, imo.

    What about an antenna for a desktop. My desktop always loses a connection, while my laptop maintains one while in my bedroom. I think it is because the desktop is in the corner surrounded by walls. I have a linksys wireless G card.

    I put Linksys's high gain antennas on my router(didn't seem to change anything)

    no reason a desktop should ever use a omni. get a directional antenna.

    I hadda put a high gain omni on my pa's PC to reach the router. But a directional would work toos. An omni is dirty cheap, so you might try that.

    it's the same price as the yagi... And the yagi is actually a professional solution.

    Um...the Cantenna is $50 and the Yagi is $90. Plus, the Yagi is pole-mount/wall-mount whereas the Cantenna is freestanding and more easily aimed (though some velcro feet on its tripod will keep it from getting blown away in the wind). I can't tell for sure, but I'm guessing the Yagi also needs power coming into it.

    Don't get me wrong, the Yagi is obviously a more robust solution and would make much more sense for a permanent installation. Problem is, it's more than he can use. He lives in an apartment; he can't go drilling holes in the wall or bolting things to the outside of the building. The Cantenna will get the job done without forfeiting his security deposit, and if he needs to move it later on, he can do it much more easily.

    wrong wrong wrong.

    your antenna has no outdoor protection. If you get a similar yagi then the price is the same. The yagi can also be mounted on a standard tripod, or screwed into whatever.

    you don't even know what you're talking about :ugh2:

    Those alternate configurations for the Yagi antenna require firsthand experience, which you apparently have, whereas the website says nothing about them and only shows it mounted one way. Thanks for clearing that up.
