The fence may not be an important factor if it is not 'too' high. Ken is right, first do a simple site survey. I suggest you use a roll of chicken wire (mesh) to check out the site first. (ANSI C63.7-1992 page 5.) To be realistic, try to keep the reference plane within +/- 4.5 cm flat. However all things being said, that will largely depends on the soil's mechnical condition. By right :-) only low bushes are acceptable in the immediate 'vicinity' of the ellipse (obstruction free area). Another way is to do a NEC (MOM) simulation to see if the fence have a significant contribution NSA of the OATS. :-) Good luck.
