With the beam antennas which have elements with different length (3-Elem. 6-40m and 4-Elem. 6-40m) and with the UB-50 beam, the driven element (the radiator) is switched when operatinf on 30 and 40m. This makes these antennas work as 1-, 2- or 3-element fullsize beams on 30/40m, as well as 2-, 3- or 4-element fullsize on 6 to 20m. The switching relay is included in the shipment and is selected automatically by the controller, depending on operating frequency.

Here are the large yagis for people with a lot of space :) Or for the regional club, companies, diplomatic offices and other users where space requirements are not the limiting factor. Fullsize beams with two or three elements on 30 and 40 m, three and four elements on the higher bands (20m to 6m). This results in excellent and powerful signals, even more important during times of low solar activity.


The large three element Yagi works as a classic fullsize three element beam on 6 to 20m. When working on 30 and 40m the radiating element is switched from the center element to the front, the antenna is now configured as a fullsize 2 element beam with one reflector. The required coaxial relay is included in the shipment, it is switched automatically by the controller.


The large four element Yagi works as a classic fullsize four element beam on 6 to 20m. When working on 30 and 40m the radiating element is switched from the shorter element to the long center element. The antenna is now configured as a fullsize 3 element beam with one director and one reflector. The required coaxial relay is included in the shipment, it is switched automatically by the controller.


These antenna models are supplied with a truss kit for the long elements and a truss kit for the boom. This kit contains three support pillars, which are installed vertically on the boom. For the 3 elem. beam two pillars sit at the ends of the boom and support the two long elements, the third support is placed in the center to support the boom. For the 4-elem. beam the center pillar also supprts the middle long element plus the boom. Guying ropes with all mechanical hardware required to install the guy wires is included.
