UHF Shrouded Dipole Side Mount 3dB Gain
Rugged UHF shrouded dipole designed for harsh, marine, and icy environments. The dipole element is housed in a pultruded fibreglass radome with black heat-shrink sheathing to assist ice shedding, while DC-grounded elements help reduce precipitation static. Built with heavy-duty aluminium boom construction, RG213 coax tail, and a compact side-mount design, the PRO-SHD3U provides a vertical radiation pattern with 3 dB gain.
Model PRO-SHD3U
The shrouded dipole provides a rugged mechanical design with a reduced surface area, making it ideal for a harsh or marine environment. To achieve this, the dipole element is shrouded in a ‘pultruded’ fibreglass radome which is sheathed with black heat shrink to assist ice shedding.
The dipole elements are 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. The boom is made from 48mm OD x 4.47mm grade 6000 aluminium tubing. A coax tail of RG213 is fed down the centre of the boom. 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.
Recommended clamp is either of the cross clamps.
