[Antennas] Can we talk about WLAN antennas here?

Fri Jul 28 19:16:49 EDT 2006

Modern laptops with internal WLAN adapters have antennas that are usually
placed in the lid beside the screen. If you open up one of the bottom
covers you should be able to see the wireless card plugged into a "mini-PCI"
slot. There are usually one or two miniature coax lines going to it. You
would need to connect the antenna here. Of course, if the wireless LAN card
is integrated onto the motherboard, then all of this falls apart.
There are point-to-point repeaters and access points that will both act as a
LAN interface as well as repeat mode for expanded coverage. These products
can also be supplied with external antenna interfaces as well. The biggest
problem with these type of devices are the cost. They are not your run of
the mill access point that you can pick up at your local PC store for 50ドル.
They generally cost in the 500ドル-1000ドル range.

I don't see why not. I am a HAM...and we all learn good things here
regardless of area of application...right?
Well I had an old laptop which had a card which had an antenna jack to
extend the range. I used it with a smallantenna outside because I can then
connect to my nighborhood while inside my aluminum-siding home. The small
antenna I used was just to overcome the coax loss at 2.4 gigahertz.
FINALLY, THE QUESTION...
My new laptop has the same problem but no antenna jack to add an outside
antenna, so,... 
1) Has anyone ideas about how to boost the antenna in these new ones? I
suspect the antenna is in the flip-up screen's enclosure.
2) Maybe an antenna outside and an equivalent of an antenna inside and near
to the laptop?
Anyone tried to do this and perhaps been successful ...before I begin to
explore home made hardware answers?
