    Hidden wifi antenna... what would work better?

    Car is 02 Toyota Celica

    Was originally thinking one of these:

    hidden inside fiberglass front or rear bumper. Probably use the magnet base to attach to the mounts for front or rear bumper.

    Then I saw, on some modder TV show... The person used something like this


    strapped to the underside of their trunk. Celica has a false parcel shelf and a big window above it, so I thought this may work well.

    But, I know the story about vertical antennas layed horizontal. So possibly either vertical antenna and just stand it up on the parcel shelf.

    Then I was looking at the "ceiling" type, like this

    Basically, I want the best, longest range reception possible. However, I don't want to permanently alter exterior of car and magnet-base would look bad. I'd consider external if I could find a fin or similar. Of the above, what would work best? Advice would be totally welcomed and appreciated.

    Strapping the antenna inside your trunk won't work very well, all the metal in there will make an excellent signal shield.

    It isn't a trunk. Celica has a hatch-back. So "trunk" is just open area with a false parcel-shelf.

    Mm, yes, I'm observant today. It may work, but having it mounted vertically would definitely be best. Horizontally probably won't work too well either.

    There are some nifty little stub antennas here: http://www.hyperlinktech.com/web/mobile_antennas.php

    Maybe get one and attach it to the underside of the air spoiler?

    Stub is the only possiblity for the outside of my car. Either underneath spoiler or suspended from the front bumper "lip". Of course, I can only find stubs that are 3dbi or below. I really want 5-7 dbi.

    Question, a vertically polarized antenna... Does it matter if it standing or inverted/suspended? Or are they the same.. wave-wize..?

    * 0l33l... you even got the color right... LMAO

    If a whip is inverted (fed from the top) then the radiation lobes will be pointing towards the ground instead of up in the air. The higher gain an antenna you use, the flatter the lobes will be.

    LOL... could you give me the english on that? I assume you mean lobes towards the ground is bad. And the higher the gain, the more important the lobes become?

    Also... is that only true for a whip. Or would stub be the same?

    Converting a vertical to a horizontal antenna loses about 20 db. A antenna with a coil in it, such as the first one pictured is good. You really don't have to worry so much about the peak lobes pointing into the ground, because most AP's you're connecting to are on ground level to 3- stories.

    Also think of where you mount it this way - line-of-sight. Any metal in the line of sight acts like a shield. So if you install it below the nspolier, youll lose connectivity, up/down left/right and forward.
