When activated, teleports cubes to the end of an attached laser beam. • Connect the sendificator to a laser with an antline,

But my attempts to connect it ? aren't working?

(notice the very faint dark blue line indicating that it won't connect)

The existing antline is to the laser catcher, notice that works.
There isn't a dedicated Antline element in BEE2, as far as I can tell? help
