| Tiivistelmä: | Parabolic antennas have been used worldwide to receive programmes through satellites. As a result of development their sizes became smaller, thus also their installation price decreased. Now different manufacturers are working on square antennas but for the time being these are rather expensive. A further step will be to develop antennas with electronic steering. |
