Antennas follow a property called reciprocity. This means that if the majority of the directivity is in one direction during transmit, during receive the directivity will be the same and in the same direction.
So in the case of the PDF you posted for the LogiLink antenna, you can see the it is directive in one direction (for both transmit and receive). If you try to pick up a signal coming from the opposite direction, the signal will be highly attenuated. This means you may or may not receive the signal but you would certainly have a much better chance by pointing the antenna in the direction of the desired signal.
There are also omnidirectional antennas that exhibit gain. These may be more suitable for you if you need to receive signals approaching the antenna from various directions. An omnidirectional antenna exhibits gain by restricting the pattern in the vertical orientation.
