They do indeed sometimes help reduce the QRN from some thunderstorms,
particularly if they are in a nearby state (higher angle) and
perpendicular
to the desired direction. But they are only 580' (1λ on 160 and a 3 dB
beamwidth of 90 degrees). And I do have one Beverage that seems to have a
degraded F/B ratio, and I need to go out there and check it out.
The top of this page shows what a highly directive antenna with clean
pattern sounds like in summer:
