It would be great if someone with knowledge of this could update the 
wikipedia DS3 article with more specific information regarding cabling. My 
limited use of DS3 has involved using RG59 cables without problems, but 
that's with very short cable distances (less than 5 meters). There is an 
wikipedia article very briefly describing RG59, but no mention of 734 or 
735. Spending a few minutes on google doesn't reveal to me the difference 
between RG59 and 734/735.

<http://www.adc.com/Library/Literature/292.pdf> mentions RG59/734/735 as 
DSX-3 cabling all of them which to me contradicts what has been said on 
this list.
