Hi,
Basically, there are multi element on a boom. Shorter element side
should point to the station. Short element is called director, longer
one is called reflector. The more elements, the more gain.- Hide quoted text -

The more elements it has the more 'pointy' or directional the antenna
will be!
In other words, using a multi element antenna, if the antenna is
pointed directly at one station, another station, off say 30 degrees
to one side in direction, may not be received at all
If signals are weak an antenna with more elements generally has more
'gain' (From the ONE desired direction!).
