You probably are using a Mininec ground under the dipole.  A low 
horizontal wire over a Mininec ground is a rule violation.  Try using a 
real ground.  Read the EZNEC help file on ground types.

Also a vertical on 160 will have an advantage that does not show on NEC 
plots.  Look up the effects of the Earth's gyro frequency.
