I've hunted antelope in Wyo for quite a few years and can tell you that antelope in the areas I've hunted in Wyo have about a 2 mile radius home range. Some bucks may have larger areas than this and some may have less. Obviously winter, rut, hunting pressure, etc can change this.
I've done quite a bit of waterhole hunting and the same bucks tend to water at the same waterhole. Especially if there is only 1 water source within their home range and it is hot/dry. Obviously when it rains they may not water at all at this waterhole (until things dry back up) and if there are quite a few water sources they may not hit the same hole. I've also noticed that they may water at first light one day and not water again for a couple days...and possibly the next time they water may be during mid day.
Things change dramatically with temperature, moisture, rut, wind, hunting pressure, and even from buck to buck, etc. One year I hunted a ranch where there was only 1 water source and I never saw a particular buck I was interested in water. I raked the waterhole right at dark and found out that the smart ole buck was watering at night!
Another place you may be able to pattern antelope is around hayfields, fencelines, etc. If you are hunting with a bow it may take several days or a week to get a buck to come within bowrange of a blind, but if a buck is using an area regularly they may wander down a fenceline, cross a particular saddle, etc.
