I agree with Joe, W4TV, but, would add the comment:
PUT THE 20M monobander on TOP of the stack .. that is .. invert it,
with the 10m on the BOTTOM.

Quoting "Joe Subich, W4TV" <lists@subich.com>:
Unless the monobanders have been designed to operate in a stack
("Christmas tree"), stacking them as closely as will be needed to
stay within your 5m mast will certainly reduce their performance.
If the monobanders have been optimized to work in a stack, use the
spacing for which they were designed.

Hi all
I need advice from some more experienced with stacking about possible setup.
Have self-standing tower abt 18 mtr, mast 50 mm (2") 5-6 metres long
Antennas are three monoband yagis as follows
20m 4el 9,5m boom
15m 5el 9,6m boom
10m 5el 7,6m boom
Does it "Christmas tree" setup working well with this monobanders?
What is your recommendation for vertical spacing between? Does 2"
mast is strong enough to support all them.
I would install lowest antenna for 20m then 15m and on the top 10m
I know that is compromise against performance and radiation
pattern, but actually cannot install another tower
Please help
Thanks in advance
Fudo, E73CQ
