[TowerTalk] 2 telrex 6m624's versus M2 6m9khw

[john at kk9a.com]

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 
beam.

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!
