Need USB adapter w/ext. antenna connector

Can anyone recommend a USB wireless adapter card with external antenna
connector, for my rig?  I'm running Linux on a Presario F756NR.
The internal card has an Atheros chipset and, using MadWiFi drivers, I have been able to do pretty much anything I wanted except boost my gain.

So I'd like to find a good USB card for it.  Will go $100 but want external antenna
port.  Also, Prism or Hermes chipset support would be best.

Can anyone recommend a solution for this problem?  The only way I know of to
boost gain is to couple an inductive cantenna to it and I have constructed one but
was unable to match it.  Atheros won't tell me where the antenna is located, or
even the card, and I don't want to take this puppy apart just yet ....

thanks

Re: Need USB adapter w/ext. antenna connector

When I was looking for a USB wireless adapter I got this one "Edimax EW7318USG", it uses the rt73usb module from the RaLink drivers. So it's not a chipset you wanted but it has an external antenna connector. It also works fine when I used it, which was just normal usage no fun stuff like package injection or other fancy stuff.

Re: Need USB adapter w/ext. antenna connector

ok thx for the recommendation.

ii assume u r running archlinux?  which drivers ru using with it?  also this came from aircrack website:

Ralink makes some nice b/g chipsets, and has been very cooperative with the open-sour"ce community to release GPL drivers. Packet injection is now fully supported under Linux on PCI/CardBus RT2500 cards, and also works on USB RT2570 devices. However, these cards are very temperamental, hard to get working, and have a tendency to work for a while then stop working for no reason. Furthermore, the RT2570 driver (such as that for the chipset inside the Linksys WUSB54Gv4) is currently unusable on big endian systems, such as the PowerPC. Cards with Ralink chipsets should not be your first choice.

There is one exception with regards to the Ralink chipsets. This is the RT73 chipset. There are excellent drivers with high injection rates for the RT73 chipset. Devices with the RT73 chipsets are recommended."

what do u think about that?

The new Alfa AWUS036E with Ralink 8187-chipset is also great.
And cheap.
