I have one where I'm hitting it at 12 miles with a -77 but the noise floor hovers at around a -87 most of the time. But that's using a 23dbi cpe. Haven't tried the UBNT 27dbi there, may make it all good.
Would 90's be a better choice? I have only one AP using the smaller UBNT 90's but haven't tried the large 90's, only the 120's.
