Not necessarily. It will depend on how high the dipole is and how it 
interacts with your terrain. My 80M vertical (quarter wave) is 
significantly better than my 35 ft high dipole almost anywhere in NA 
-- except within about 200 miles. The reason, I believe, is that 
I've got a ridge to the North, East, and SE that affects the dipole 
more than the vertical. HFTA predicts that the dipole will be 3-6 dB 
better if I raise it to 100 ft, but the vertical is running 6-10 dB 
better than the dipole at 35 ft!
