DAB Double Dipole Band 3

DAB Double Dipole Band 3

The linearly polarised ADC V90 DAB Double Dipole Band 3 Antenna operates from 217 MHz to 230 MHz. Developed as a versatile, robust, and reliable vertically or horizontally polarised antenna module. It forms the basis of a range of standard and custom-designed arrays. 

Multiple coverage patterns are configurable. Double Dipole Band 3 Antenna panels are mountable on new or existing structures. Horizontal patterns install in a “four-around” arrangement.  However, a configuration for directional arrays is also available.

DAB Double Dipole Band 3 Design

Radiating elements are 38.1mm (1 1/2”) in diameter and manufactured from a hot-dipped galvanized steel tube. Mounting is on a quarter wavelength in front of a galvanized steel screening frame. Also, the welded construction gives a robust and efficient screen combined with low effective wind area. The main members provide a versatile means of fixing the panel to a variety of structures. The use of standard clamps without the need for complex and expensive steelwork is standard. GRP covers provide weather protection for the dipole feed points.

Horizontal Radiation Patterns

The datasheet shows the various radiation patterns.  Many customised patterns are available. These provide optimum coverage in specific cases. Moreover, the power division between the faces of the array is adjustable.  Moreover, the relative phase of the current to each face can also be varied. The geometry of the panel positions relative to one another may also be varied. The DAB Double Dipole Band 3 provides a flexible design that provides economical customisation.

Vertical Radiation Patterns

The datasheet also displays several vertical radiation patterns. Both beam tilt and null fill are also configurable for each pattern. However, alternative values may readily be provided. The branch feeder system offers excellent broadband pattern stability.
