For a flat SWR you will have to set the wires at a 120° vee, then tune for flat.

- If you cut or extend the wire to tune for flat at a lesser or greater vee angle you will actually be increasing the rectance and losing performance. Not a big loss but better to cut it to the right length and live with up to a 1.5:1 SWR, depending on the vee angle.

At a 90° vee (37ohms, 1.5:1 SWR) you'll have equal energy in both the vertical & horizontal polarizations in all directions ('spherical pattern'?) unless you're after more broadside horizontal performance.
