I've had at around ~450 feet, but you have to change the LBO/Cable length in the CSU. -----Original Message----- From: Robert E.

I need to run a DS3 across our parking lot.. Seriously.

What's the max length I can use coax for (I know, gotta use a GID), and what's the best brand/type of coax I can use? It'll be through innerduct.. Looking for some real world answers from people that do a LOT more of this than me.. (It might take 350-400 feet).

The textbook limit is 450' for 735 cable. I've had poor luck pushing the limit, and don't know offhand if using some other flavor of 75 ohm cable buys you anything. Were I in your position, I'd have glass pulled and use a coax to fiber media converter such as http://www6.adc.com/ecom/hier?NODE=OND68947, http://www.versitron.com/DS3T3.html, or http://www.rad-direct.com/DATASHEET/FOM-T3.pdf (the latter of which I've used personally) on each end. No, it's not the cheap way to do it, but it eliminates ground loops and other such nastiness that can ruin your whole day. ---Rob
