A 150 foot boom ( say 20
elements for example) beam might be perfect for picking up t he lower
angle, which is what I thought you were looking for. The t hree
element beam will bring in higher angle signals as the lobe will
have
a higher angle. A dipole will likely have even a higher, po ssibly a
NVIS angle. ...................................


Dunno...I've never compared super long yagi's vs short ones, but I
don't
think boom length has a drastic effect on the takeoff angle...The
height above
ground is what really determines that...Same for a dipole...A dipole
has a very
low takeoff angle *if* it's high enough..The various yagi's takeoff
angles *should*
be about the same as a dipole at that same height...Or seems to me,
without
looking into it farther. MK
