The nominal impedance of a half-wave dipole at least one half wavelength above ground is approximately 72 ohms.
The reason most modern radios have a 50 output impedance is due to the preponderance of 50-52 ohm coax cable available since the Korean war. The mismatch between 50 ohm radios and a 72 ohm antenna is approximately less than 1.5:1. Virtually all modern radios can easily handle this minor mismatch.
