Product Information
  • Overview

Ultrabeam UB640-VL1.1 6 – 40m

  •  boom length
  • 11m max. element length
  • 1 element fullsize on 6–20m
  • 1 element folded 30 & 40m

Finally QRV on 30 and 40m!

A small 2 element fullsize beam for the bands from 6 to 20m, and a fullsize rotary dipole on 30 and 40m! And all that without causing too much distress for the neighbours... Ultrabeam changed the matching circuit for the driven element to achieve always a perfect 50 Ω match. This results in a high efficiency also on the 30 and 40m band. On the bands 6 to 20m this yagi achieves the same excellent results as the classic 2 element Ultrabeam.

Like the other 'large' Ultrabeam antennas, the UB 2el 6-40 uses a square boom for high stability. And it uses the same super massive boom plates for the motor units and the elements, resulting in a superb mechanical stability. The balun of the driven element can be switched from 25 to 50 Ohm to match the configuration as rotary dipole as well as a Yagi configuration. For this reason this Ultrabeam model requires a 10 wire control cable.

For this antenna we offer an optional truss kit for the elements. This kit contains a support pillar, which is installed vertically on the boom, plus guying ropes with all mechanical hardware required to install the guy wires to the extremities of the boom.
