Hi,

I am getting ready to set up a Pacific 20/40 dipole in an inverted V configuration... however due to my property limitations, I am not able to set up the elements on the azimuth at 180 degrees apart. More like 100 degrees or so. So, looking down from the sky, say the elements are at the 12 o'clock and 4'oclock position, what should I expect? I don't care about direction, I just wonder how it will behave, or what effect this would have on the impedance.

Thanks in advance and 73.

It will lower the feedpoint impedance somewhat.  If that's an issue then run the leg as far as you can
in a direction closer to 180 degrees before bending it 90 degrees along the edge of the house / lot /
whatever.  Bending the ends has less effect on performance and feedpoint impedance than bending
it in the middle.

I suspect it will work fine.

Here is the model information:

www.qsl.net/kk4obi/Center-fed%20V-dipoles%20Lateral.html

This applies to your resonant 40m half-wave fed at a half-wave high, not to the 20m first harmonic.  The model used is included if you wish to adjust it for your layout.
