Does anybody know the realistic speed limit of data transfer that can
reliably be sent over RG-58 (or even the 75-ohm RG-59).  I think
thin Ethernet uses the RG-58.  Is Ethernet close to the limits of this
type of cable or if a different standard was adopted, could the performance
upscaled a magnitude or two?

[Personally I think LANS should be able to go lot faster than then
the 10 megabit/sec. standard Ethernet---Anybody actually know?  I'm
basing this guess on the fact that I'm able to receive 40 channles of
real time videa over RG-59(just like RG-58 only different impedence) via
local cable.   If each station requires about 6MHz of bandwidth alone,
than ethernet should be no where near the limits of the RG-58 cable.

Am I messed up or on the right track?
Please comment, easy on the flames.....
