I concur regarding the Telrex design. They are old designs with equally
spaced elements and unfortunately since the elements go though the boom,
they are difficult to optimize. I sold all of mine years ago. I am not
familiar with 6m propagation and what advantages stacking may have, but as
far as peak gain goes, you are probably better off with the single 9el M2

In my opinion any old telrex should be run through an optimizer before being
put back up on a tower. I tested and retuned 3,4,and 6 ele 20m, 8ele 15m,
and a big 10m one... they all needed major retuning, the 10m one was a
better 11m antenna than 10m. when the 6 element 20m was optimized one whole
element was virtually worthless, on the 8 ele 15m the optimizer removed 3
elements to make it better!
