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.
