ABSTRACT:
An upright tubular housing has a lower end portion connectable to the ground, and an upper end portion. Arrangements for emitting and/or receiving light pulses are mounted in the lower end portion of the housing and a deflecting mirror is mounted in the upper end portion for deflecting the light pulses between a vertical and a substantially horizontal path. A break-away zone is formed in the lower end portion in the region where the same is connectable to the ground so that in the event of collision with an aircraft the housing will break away at this zone to thereby reduce the collision danger to the aircraft.
