Two parallel Beverage antennas spaced an eighth to quarter wave apart with an eighth to
quarter wave stagger in the desired direction can be combined to improve front-to-back ratio
or steer nulls to the direction of unwanted signals or noise.
The best system is often found by planning, although it is often worth experimenting.
Using this type of directional phased antenna array you may record phase settings to null stations
from known directions. It is then possible to make a direction chart. With optimal antenna spacing it
is possible to tell direction within several degrees.
