Well, I'm not just building *any* WiFi setup - I researched a bit and
found
on eBay what is generally agreed on to be one of the top 5 internal
802.11
cards. With up to 250mw output and external antenna, I plan on diving
into
a new hobby - wardriving.

I could just buy a USB WiFi adapter and crack open the case and hack it
with an external antenna but from what I've seen, both the low output
and
poor rx sensitivity seem to be quite common with these devices and that
is not what I want.

I did remember a bookmarked site which calculated the info I needed.
Turns
out that my coax in question will have about 1.7 db loss at 5ghz. Not
too bad.

Still, if anyone knows of a coax that is better than RG174 while being
about
the same size, please chime in with your comments!
