Here goes.
Sage is not tight sea of brush, it has structure, maybe less defined than farmland in the Midwest. But there are openings, grass filled drainages, bowls, ridges, gullies, and where your at exposed basalt outcroppings. Learning to use natural features for blocking, roads, irrigation canals, ridges, farm fields can all be used to block coyotes. They have a tendency to stay in the sage where they are safe rather than crossing open spaces to get to our caller. I have a saying, "It is easier to call coyotes in the brush than try and call them out of it". Find some elevation that lets you look down into the sage. Hunt openings in the sage. Ariel views of the area you plan to hunt are good to find openings, Google Earth, Onx maps and even real-estate sights have satellite views of the ground. Scouting out stands before you hunt can be a big help as you are not wandering around in the sage trying to find a stand on the day you want to hunt.
Remote callers are heaven sent in the sage as the action is going to be close and you want the coyote focused on the caller not you. I find directional callers(speakers facing one direction) a big help also, I find many of the responding coyote will come in from the direction the caller is facing. this might be a phenomena of the fact I've been doing this long enough that I have a pretty good idea where the critter will be coming from and instinctively face my caller that direction.
Cross wind is your friend, facing down wind will have a coyote in your scent cone long before you ever see him. Facing into the wind if you can get your caller out far enough that he can circle downwind and be between you and the caller.
With crosswinds or quartering winds I will set my caller on the upwind side of the opening and set up so I can see the coyote poke his head out of the brush to look into the opening or trot up the length of the opening. It doesn't always work, I did have a coyote sit down four feet from me and look out and watch the same opening I was.
Decoys are a something that can be a help or hindrance, I find spinning decoys on the ground can be a problem a coyote coming through the sage can't see and is relying on his ears and nose, coming out of the brush and finding something spinning in his face can really spook him. Small decoys off the ground where they can be seen from a distance seem to work better for me.
Guns and optics, ranges are going to be shorter most of the time well under 100 yards and sometimes as close as your shoe laces, sounds like shotguns but there will be many times the coyote will hang up at the edge of an opening or you will find a plase that the sage is thinner and you can see them coming farther. I like to use combo guns O/U rifle/shotgun or fast handling rifle with scope that have very large FOV's for faster target acquisition and being able to track moving animals in the sage and see enough ahead of him to spot and opening for a shot before he gets there. I really like scopes with at least a 45' FOV and prefer a lot more, my 1-4x20's got to 100' and still have the 4x to shoot accurately out to 300 yards so my combos wear 1-4x20's , my bolt action 1.5-6x40's and I'm playing with 2-12x42's with a 55" FOV on the bottom end.
Good luck to you and have fun.
Fun in the sage
There is a lot of different sage also, tops of ridge where water runs off will a lot of time have sage that is less than knee high, lower places can have shoulder high sage.
Large flats of sage like this can be a sanctuary for coyotes as many hunters bypass it because they can't see into the next zip code.
There are places to hunt this you just have to find them.
