Buxcomm 7510CT2FD Manual for Terminated Folded Dipole Installation

I have the Buxcomm 7510CT2FD and noticed that the webpage for it has been taken offline. Below is the manual for reference.

Also came across interesting specs for the Codan 411 TERMINATED FOLDED DIPOLE ANTENNA which is a nice comparison of the efficiency of a T2FD versus a Dipole in free space at 1/4 wavelength above ground - a requirement that most dipole installations do not fulfill - versus a T2FD at 10m / 33 feet. Seems like the T2FD is not such an inferior antenna...
