The dipole element is DC grounded which assists reduction of precipitation static. The centre feed exits through the heavy duty, element to boom casting. This casting is then attached to the boom with three radial bolts to provide reliable fixing. All booms for the UHF DU3-SH Shrouded Dipoles use 48mm OD x 4.5mm grade 6063-T6 aluminium tubing. A coax tail of RG213 is fed down the centre of the boom and terminates with an N plug connector. Standard tail length is 1.5m from the boom exit.
These dipoles have a vertical radiation pattern with 3dB gain in a compact dipole side mount package.
