UHF Shrouded Dipole Stacked Arrays

Models DU3-SA & DU6-SA

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.
