It's do-able, but you have to watch the loss from the extended cabling runs. Resist the temptation to use handmade cables - stick with the approved pre-fab stuff. There is a a great deal of loss at these freqs and everything must be nearly perfect.
Generally plan on using higher-gain antennas (omnis or sector antennas).
Of course, a good site survey should be conducted to ensure adequate coverage.
Good Luck
