Thanks to Xavier / F6FKQ for his comments and help in testing this adapter with the Ultrabeam antenna.

The tilt plate the ultra beam and the 3 antennas for vhf uhf and shf are mounted and tested with the newly motorized versa tower. Very impressive system. Your tilt plate works perfectly during the verticalization of the tower allowing à very smooth erection. Pictures will follow very soon once everything is in order. But i can tell you thanks to the tilt plate the antennas erection and maintenance is a pleasure and so safe.
