yes, I've seen people trying to use rg58 and rg59 (CB and cable TV coax)
for 802.11, oh the horrors....

The problem that I find most annoying is the fact that you can't get MMCX
connectors for larger diameter cable, so you have to make a short pigtail,
and then connect to a larger diameter cable with connectors that are
common to both. This leads to loss, i've heard a rule of thumb of 1 dB.

This will be more important in 802.11a installations: cable losses are
higher at higher frequencies. In addition, amplifiers are more expensive,
and Line-Of-Sight is more important on these bands.
