David, You can run upto 1.5 miles on a lx fiber based solution but will likely require a skilled installer to setup that much cable for you. Depending on your locale I am may be able to put connect you to a supplier. Have you considered a wireless direct beam solution? Especially considering the 'temporary' nature of this install. ___ Cheers, Mikel King CEO, Olivent Technologies follow-me http://twitter.com/mikelking ...... Original Message .......
