A half-wave dipole is the antenna everything else is measured against. The usual 468/f shortcut hides a velocity factor that only suits one wire thickness — this uses the real wavelength and lets you pick your material.
Cut a half-wave dipole to your band and your wire.
A half-wave dipole is the reference antenna — simple, efficient, and the thing every other antenna is measured against.
These are cut-to-resonance lengths in free space. Real height, nearby metal and ground all shift the exact resonant point — the meter is the final authority.
