[50mhz] 6 meter yagi question

[John Geiger]

If your mounting location for a 6 meter beam was less than optimal-on a
roof tripod, maybe 25 feet above the ground, with the antenna being 3 feet
or so above the roof of the house, would be there much advantage of going
with a 5 or 6 element beam over a 3 element beam?  Is the location going to
compromise the antenna performance enough that the extra performance of the
larger antenna wouldn't be realized.

A 3 element beam on the roof would be an improvement over what I have now.
Back in 2018 I was copying plenty of EU and JA stations on 6 meter FT8, but
they were not copying my 100 watts.  I have worked one JA since on FT8, but
no EUs. I have worked about 10 different EU countries in the past on 6m
CW.  I am guessing the extra QRM that comes with everyone doing FT8 on the
same frequency is making this harder, and am looking for a way to improve
my 6 meter performance further.
