An example may be found in microwaves. The RSGB 3rd edition of "VHF-UHF
Manual" has a dipole dishfeed for the 23 cm band on page 8.67.

23 cm is 9 inches. The dipole is 4 & 7/16 inches tip-to-tip, or just 5%
short of 1/2-wavelength as expected for "end effects".

The tip-to-tip length of a dipole need not be adjusted for feedline
spacing.
