Currently the top loop is at only 20ft but I am making many contacts. Soon
however they will be placed off a sidearm on the tower.
The top loop could then be as high as 80 ft.

I have read and read about this topic. Does anyone have any first hand
knowledge of 6M height above ground comparisons especially for stacked
loops? Thanks....

You really want the lower of the two higher than 20ft.

It's really simple, higher is better. We are talking VHF and if there
is nothing going on propagation wise then height above average terrain
determines what your radio horizon will be. For that higher wins.

Simply put, 80ft will be much better than 20 and only slightly better
than 40.
