Greg: In that light, wouldn't circular polarizaion be the best solution since any reflection of a CP polarized changes its twist, hence giving a CP antenna 20+ db rejection of the 1st order multi-path?
I guess the downside here though is I'm not aware of any off the shelf CP antennas with 24 dBi gain. Still, even though it is fairly clear what the problem is, we still do not know the link margin to begin with. It sounds like it is just a 1megabit link on the peaks, hence I'm suspecting we have a poor link margin to begin with. The "quick solution" may be as simple as replacing the WAP11's with some AP's/clients with hotter recievers. Otherwise it will be up and down the towers and adding a diversity dish possibly.
