I have had the same experience on 160M working JA. I have a vertical
that gives me a dB or two in that direction, but I don't use it much for
that reason. The only time I want rear rejection is for receiving to
minimize noise. Indeed, I know serious contesters with multiple yagis
for the same band who often point one at the DX with 1400W and another
at their competition with 100W.
