NB, below are my two overlays of the New Vector 4k, a .64 and .625 wave radiators at 36' feet and at 50' feet in height above average Earth.

These models do not include matching. The Vector models at both heights show SWR near 1.50:1 at both heights so it looks as the antenna does not need much transformation in order to match. The other two models show <>35.0:1 SWR and need matching.

We see here that there is not much difference in performance, except it looks like the Vector does better higher up than the other two. I did not include the Imax with 62" radials, but it is worth noting at 36' feet it shows more gain, by .36 dbi, than all the others at 36' feet.

In my real world experience with these types of antennas my antenna signal reports tend to support these similarities in results...I just don't see the signal difference that others report, and thus I don't see the gain differences either.

If I didn't see this using my modeling...I would have only my words and my signal reports I've posted to support my claims.
