You can buy them at Tessco, I'm pretty sure. Stick with Heliax (r) type cables (hard line) for those distances, and use 1 5/8 minimum. The loss is amazing at anything above 450 MHz. Look at any cell tower and you will see what you need to use, then count on twice the loss if you use 2.4 or many more times that at 5.2 or 5.8 Look at a price range of tens of $ a foot, once installed properly.
This brings you to the next obvious issue. Now for the lesson in RADIO. You have degraded your system so much by adding loss, you can figure that your antenna just magically became 0 dB gain instead of what it was. You may even totally offset the antenna gain and be upside down (as they say at the car dealer down the street). So go buy the best antenna you can, with the most gain possible. Of course now that moves us to the next step. Can't get a high gain antenna because now the tower company wants more rent, or the wind load is too high, or the pattern is too narrow. On to the next step- More APs so you can cover the areas that your new high-gain antennas leave out. Then, more hard line, then more $$$ etc. Or you can take the illegal, easy way out. Buy Amp. Create noise, Violate Part 15 and your radio's certification. Leave yourself open for a fine. Sounds to me that you are better off doing what most discovered the hard way: Leave the radios up top, do a great installation job, weatherproof, lightning protect, and enjoy the power you paid so dearly per milliwatt for in the first place!
