A. Use a (better) antenna. (See 9.7 and 9.8 below)
B. Use a (more) directional antenna. (See 9.7 and 9.8 below)
C. Aim your directional antenna. Rhombics are ungainly to move,
but Yagis and dipoles are small enough to point right at
the station. With the dipole, to tune in a station to
the East, run the antenna North-South. With a Yagi,
point the individual elements North-South with the
smallest element on the East end.
