UHF Shrouded Dipole Stacked Arrays
Rugged UHF stacked arrays designed for flexible configurations with minimal hardware. Based on the PRO-SHDU shrouded dipole, each array features UV-protected PVC radomes, anodised boom construction, RG213 coax tail feed, and end-mount clamps for mounting to 48 mm OD tube or timber pole. Down tilt can be achieved using delay lines in the feed system.
Models PRO-SHDU-SA3 & PRO-SHDU-SA6
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.
Each dipole is fitted with an End Mount Clamp which enables it to be clamped to a vertical 48mm OD tube or screwed to a wooden pole.
Down tilt can be provided by inserting delay lines in the feed system.
Items supplied for a PRO-SHDU-SA3 are 2 x dipoles (PRO-SHDU) and 1 x power divider (PD2)
Items supplied for a PRO-SHDU-SA6 are 4 x dipoles (PRO-SHDU) and 1 x power divider (PD4)
