It is generally assumed that bending a whip antenna to a military style will improve NVIS performance because there is "horizontal part".
But that doesn't seem to be the case. Although a whip is abt 5
meter long the NVIS performance seems to be poor at least on lower bands.
A roof corner mount shorter vertical whip antenna seems to outperform a miltary style bent whip in NVIS contacts, see more here.

Simple model of a military style bent whip antenna.
Total length of the whip is 5.3 meters. |

Poor NVIS performance on 80 meter -28dBi upward

Poor NVIS performance on 60 meter -24dBi upward

Moderate NVIS performance on 40 meter -19dBi upward
