[TowerTalk] Coaxial Moxon

[AD5VJ Bob]

That is correct and is exactly why a double bazooka is shorter than a normal dipole. I have looked at the pics and dont see why the
antenna would not work. Whether it works as advertised, who knows until you do one.

Personally, I think it would be fun to try it and see what happens with measured data :0)
