You should download the program YTAD from the ARRL's file
server. You could also purchase the ARRL Antenna Manual and
get an updated version of this program, YT, packaged with the
manual. Both programs are very helpful in determining antenna
patterns in mountainous terrain. These programs are also a lot
of fun to play with.
