Why use omni-directional antennas for a point to point link, not only are you 
wasting power output in directions you dont need it, but you are going to get 
noise from directions you don't need to listen to. Not to mention it's 
irresponsible use of a free spectrum that's to be shared responsibly by all, 
ie. one should use as little power focused in the smallest area possible to 
get the job done.

You have to either put them in Point to Point mode or one in AP and one in 
client mode. A client (endpoint) access point should never have an 
omni-directional antenna on it.

How long are your cable runs.

Yes - that's what you should be using. You'll have much better results 
although you'll have to aim them up. using 24dBi directionals you'll likely 
have less noise to deal with, and have 18 more dB of signal between your 
points.

I would also recommend using the point to multipoint mode of the AP's, not 
802.11 AP/Client mode.

As long as you have a clear line of sight, and guessing 5dB of cable loss on 
each end you should easily be able to make the link work with 15dBI 
directional antenna's. Remember - smaller is better as long as the link works 
because you won't be picking up garbage noise in your link from distant 
areas, and you won't be putting your overpower signal into a place that you 
might want to put something else up later.
