Eight-Lug HF Vertical Ground Radial Hub
A 120 mm ground-radial hub that clamps onto 1/2" EMT conduit (17.9 mm OD) at the base of an HF vertical antenna. It has eight M5 lugs on a 92 mm circle, each with a captured nut, a groove for a bus wire, and a notch at the rim where the radial wire leaves, so you can fit and service up to eight radials in a tidy way.
