Basically a funnel is a place that deer are forced or prefer to pass through. Deer generally take the easiest route possible while still staying in some type of cover, generally. A good example of a man made funnel would be a fence that runs some distance. Well to funnel deer to your set up make a pass in the fence at some point either my cutting or pushing the fence down. Set a stand up near the pass and smoke them when they come through.

Another example of a funnel is a natural one like the one I hunt. I hunt at the top of a gradual slope that leads down to a river, deer don't try to cross the river because it is about 200 yds wide and probably 20 ft deep in some places. What makes it a funnel is that there is a drainage ditch that runs almost to the top of slope where I'm set up at down to the bottom where it empties in to the river. This drainage ditch runs a few hundred yards and is pretty deep with steep walls, deer generally won't pass through it, instead they pass at the top where the ditch ends and I am set up.
