Inverted V angle

[tba02]

Most literature on inverted V antennas gives a angle range of 60-120 degrees included. I have been searching, to no avail, what the angle's affect is on the impedance of the antenna. Does anyone out there know of a graph or chart of some sort that shows the relationship between angle and impedance and where to find it?

* The degrees of the angle included between each arm is twice the angle number. For example, at the 45° number the included angle is 2 * 45 = 90°... a right angle. Same at the 135° number. 2 * 135 = 270°, where 360 - 270 = 90°. Altenatively, use negative angles. 135 - 180 = -45°. Then, 2 * -45 = 90°.

And the saying is confirmed. A pictures is worth a thousand words. It would take me more than 1000 I think to explain what that chart reflects. Good find.

Being using an inverted "V" for over 40 at about a 90 degree angle, now I know why it works so good!

I had good result with 20m, 15, &10m with my inverted fan dipole, now I know why.
