It is true there are 8 elements on 10m meters, but they are there because of
the element-band interactions not because that would provide us more gain or
make a better antenna :)
Separate feedlines in this era are under my opinion not any an big issue any
more as firstly even with one feedline you can work full SO2R (some state of
the art filters can do that easily......)....secondly in multiple stack
array (let's assume you have 3 steppir's....with proper switching you always
have at least one antenna into 2nd radio......
So the only issue is the performance/reliability?
Thanks for answer
