Dual Beam Pro Specifications

The Dual Beam Pro is constructed from aluminium alloy tubes with an insulating GRP rod in the centre. A 4:1 voltage transformer provides a balanced to unbalanced interface to the feeder and transforms the impedance to give a broad match across the HF bands.

Radiation pattern

The Dual Beam Pro has 2 main radiation lobes transmitting perpendicular to the main elements.

The typical directional gain relative to a theoretical antenna radiating equally in all directions (Isotropic gain) is:

20m: 6.6dBi @ 29 degrees elevation

15m: 7.6dBi @ 19 degrees elevation

10m: 7.4dBi @ 15 degrees elevation
