I am using an ASUS EEE pc for my carputer. The wireless adapter is an Atheros ar5bxb63. There are two wires for the antenna, Im not sure of if i have to worry about polarity or what type of signal these two wires carry. The wires were going into the laptops lcd and connected to two small separate pieces of metal. I want to extend these wires to the antenna that my car uses. Is this possible? My car antenna only has one wire... My only problem is I'm not sure which wire to connect to where. If i cant do this than i will simply extend the wires and put the two small metal pieces under my antenna on my roof ( i have a shark fin antenna)
I also own a eee-pc and want to upgrade its ability to detect and connect to wlan here and there while I am cruising in town and suburbs.
i think the way to go is have an usb dongle on the roof with a external antenna connector (just to have an open option for improvement in case we would need more signal sensitivity).
It is known that an usb dongle on a sort of mast is far better that any laptopn builtin wifi system.

a long cable transporting (very) low level unamplified signal from an antenna to a receiver is imho very far from optimal.
Most of the coax thats included with those omni-directional magmounts is fairly low end rg-58 or LMR-100, which has a relatively high loss for runs over 6 feet at 2.4-2.5 ghz. I think thats what raxy was hinting at.
Personally, I'm a fan of the engenius/senao products. Fairly high output and high recieve sensitivity. My EUB-362(ext) USB wireless device (200mW) hits a 400mW Engenius AP, both inside buildings, at a half mile with a really strong signal using the included omni-directional antennas. You could safely run either one through 6-10' of even LMR100 without a problem if you were experiencing a weak signal..LMR200 or better would be best though.
i totally agre. I am using Senao mini-PCI 54G hooked up to external antenna like the one sold on mp3car. I am picking up APs from up to 1km away. I used it to hook up to my own AP at home, 8 storeys up.
