Will a directional antenna guarantee longer reception periods then a standard antenna?
May I ask for the specs for one of this directional antennas to use with RTL-SDR?

Provided it's pointed in the right direction, and of the right polarity, then a more directional antenna will have higher gain and allow you to successfully demodulate the signal at a lower threshold than had you used a less directional antenna.
Of course the issue with satellites is the things are always moving, so getting them pointed in the right direction can be difficult. So you have a design compromise to make: do you want it to be able to receive weaker signals, or be less critical of aiming?

The RTL-SDR does not require any special antenna. Any antenna with the right connector, and designed to operate at your desired frequency, should work fine.
