The jury is in. The same QTH, the same time, the same configuration (inverted Vee), same height above ground at the apex. There is no significant edge for the link dipole in performance. The EFHW wins on convenience, ease of deployment, weight (EFHW 160 grams, Link Dipole is 200 grams).
Link Dipole is a Home Brew
