The receive part of the penalty, from a lossy antenna, only applies if
the dominant noise source is after the point of attenuation. That's not
generally true at HF.
(I wonder if, at microwave frequencies, it is possible to use
circulators and isolators to put passive losses in on only the transmit
path.)

Unless its something like a log periodic, I think anything with those
frequency/SWR specs can only do it with high resistive losses. It
reminds me of the HF dipole B&W makes for the military: it is designed
to appear to have a low SWR by having 3 db of resistive losses. The
military considered that an acceptable design. Remember, antenna
losses affect TX and RX, so that's 6 db system loss.
