The uplink is the transmitter than sends the data up to the satellite. This can take the form of a dish or a highly directional antenna. You typically see these directional antennas mounted on telescoping poles mounted on the top of TV station news vans.

Non-directional bonds occur in metals as valence electrons are attracted to the nuclei of neighbouring atoms, however, this attraction is not in any particular direction giving birth to the phrase 'non-directional'. This is what gives metals there malleability or ability to be moulded into shape. Directional bonds are the opposite, such as in an ionic substance where the positive ions are strongly attracted to negative ions forming a 3 dimensional lattice. This is why solids such as table salt is not malleable, it is an ionic compound with directional bonds.
The correct adjective form for the noun direction is 'directional'. However, the word direction is used casually as an adjective, for example 'direction signals' or 'direction markers', but they should be 'directional signals' and 'directional markers'.
