When the original signal and reflected signal reach a location in phase with
each other they combine in a way that strengthens the signal. However,
when original and reflected signals reach a location out of phase they
combine to produce a weak signal and theoretically can cancel each other
out completely to produce no signal.
It is important to understand that reflected signals don't always cause the
desired signal to be weakened. If it appears as though the signal is good in
some patches and very poor in others when there is no significant
difference in distance from the base you may be experiencing the effects
of reflection interference, possibly even an interference pattern from
another source such as a mobile/cell tower.
