Just read up on the specs of the 362. If you open the case there's an external antenna connector. You could buy an external antenna, mount it in the window and leave the 362 next to the laptop or hub. I know a source in San Antonio that can make you anantenna cable any length/any connectors/any antenna, i.e., built to your needs so all you see above the dash is the antenna. (Stick a 5 or 8dB antenna next to or in your window pillar and watch that sucker talk )
OBTW, search eBay for senao 362 - there's on seller with 44 available at $60.
