I've been modeling V beams off and on for a few years now, and never
can seem to get one that has useful gain.

Has anyone seen a successful model anyplace of a two or three wave V
with good gain??

Hi Tom,
I have a model of a 5 wavelength 24MHz Vee beam in AO- I can send the
file
if it is useful to you. AO reports 11dBi free space gain. Included angle
appears to be 44 degrees.

I don't have AO Dave, so a description will work.

That sounds like the problem I am seeing. With a 3-5 WL long V, I have
about the same gain as a three element Yagi. But I'll still try to
model your antenna with 5wl legs and 44 degree angle. Thanks.

Hi Tom et al,

This is from the AO library:
F=24.94

The vertex is at the origin: 0,0
X,Y of 1st leg is 185.44', -74.92' #12 wire
X,Y of 2nd leg is 185.44', 74.92' #12 wire

Fed at the origin and modeled in free space

AO reports
Z= 255- J706
Forward gain= 11.34dBi
F/B 2.70dB


Hope this is useful,
