greater distance than any card built into your laptop.    Externally
mounted, the vendor claims up to 1 mile range.  It's powered via your

Works with Mac's or PC's, Great for stealth camping.

I have no relation to this company, just thought it would be a useful
Westy upgrade for those of you that travel with laptops.

If anyone has bought one, please share your experiences...
