The UHF Shrouded dipole range covers single dipole, side mounts and stacked arrays.
UHF SHROUDED DIPOLE
This model provides a rugged mechanical design ideal for the harsh environment.
The dipole assembly is housed in a UV protected PVC plastic radome. The centre feed is taken out through a ‘Tee’ attached to a 38mm OD x 3mm wall anodised aluminium boom. An RG213 coax tail is fed down the centre of the boom and terminated with an N plug connector. The standard tail length is 1m from the boom exit. The DU-SH dipole is supplied with a fitted End Mount Clamp (CLEM) designed for mounting to a vertical 48mm OD tube.
UHF SHROUDED DIPOLE STACKED ARRAYS
The UHF stacked array is designed to be used in different configurations, with minimal hardware. Like the UHF Shrouded Dipole, these arrays provide for rugged mechanical design ideal for the harsh environment.
The Dipole assembly is housed in a UV protected PVC plastic radome. The centre feed is taken out through a Tee fixed to a 38mm OD x 3mm wall anodised boom. A RG213 coax tail is fed down the centre of the boom and terminated with an N plug connector.
Each Dipole is fitted with an End Mount Clamp (CLEM) which enables it to be clamped to a vertical 48 mm OD tube or screwed to a wooden pole. Downtilt can be provided by inserting delay lines in the feed system.
Please note: Vertical support shown is extra.
UHF SHROUDED DIPOLE SIDE MOUNT (3DB GAIN)
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.
These dipoles have a vertical radiation pattern with 3dB gain in a compact dipole side mount package.
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.
