I think we paid about $120.00 per thousand and it is outdoor shielded
w/drain wire and gel filled.

Subject: [WISPA] Shielded Cat 5

I am sure it has been asked before but...
I need a good source for shielded Cat 5 (with a drain wire). Can you 
tell me who to call and what the price is per 1000'? I think we paid 
some ridiculous amount for it recently. What's the best you have seen 
and who has it?
Thanks guys,
Scriv
