For a couple of years I had three homebrew monobanders on a single tower
at P40A and it worked nicely. I had the 20m and 15m beams on the mast and
the 10m beam was on a ring rotator well below the other antennas. I later
added a second tower and moved things around and added a 40m beam. Having
seperate monobanders was nice for SO2R, but there are well designed
interlaced antennas and triplexers on the marked now that will accomplish
the same thing.

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
