Half-wave Dipole33.1 ft / 10.1 m
Quarter-wave Vertical16.5 ft / 5.0 m
Full-wave Loop71.0 ft / 21.6 m
J-Pole (long section)16.0 ft / 4.9 m

5/8-wave Vertical41.3 ft / 12.6 m
Formula reference
Dipole (ft) = 468 / freq (MHz)
Vertical (ft) = 234 / freq (MHz)
Full-wave loop (ft) = 1005 / freq (MHz)
5/8-wave (ft) = 585 / freq (MHz)
Constant 468 accounts for end effect (≈0.95× of theoretical half-wave). All figures are starting points — trim by 1–2% and use an antenna analyzer to find resonance.
