That's a shame.  I had to recrimp some RG6 the other day and mechanically
it's the sort of stuff I wish was good for 2.4GHz.  It's quad shielded and
and is full of a sticky goop in the shield which I presume is to stop any
sort of water ingress, as you would get in a telecoms pit or on a pole.  
And F-connectors couldn't be easier to cut and crimp, no fangled
soldering.  So I checked out the RG6 specs and unfortunately it's 75ohm
and rated at 26dB (from memory) loss per 100m at 1GHz.  I hate to think
how it is at 2.4GHz.  Ho hum.  It might be alright with WiFi for short 
runs...

Tony Langdon - have you used RG6 in the wrong way?
