.. it's dependent on whatever real world conditions it's built in. It could be as low as 30-40 ohms, if it's close to the ground or other objects. It could be higher depending on what you've used to build the dipole.
It's the real-world that always gets me after modeling.
A quick visualization aid to help the op might be to envision the perfect horizontal or vertical dipole in free space as having 75 ohms impedance.
Now start bending the elements out of a straight line. For example lets change a perfectly vertical dipole to one where half of it is now horizontal. ie, a 1/4 vertical, with a 1/4 wave horizontal "radial" if you will. 36 ohms impedance.
Split the difference, where the 1/4 wave horizontal section is angled down 45 degrees. 50 ohms. One of the reasons why ground plane verticals usually have radials sloping down at 45 degrees or so, rather than being perfectly horizontal. I've seen guys take this to the extreme trying to match up to 75 ohm coax, and have radials angled down at 70 degrees or so ... approaching pure vertical dipole or a sleeve dipole at this point...
When getting out of free space, the environment and building materials, typically very thin or very thick has a major impact as well as the feedpoint itself getting closer to ground changing these values in the real world...
