UB-20MX

 

The UB-20MX is a very compact antenna solution for the bands from 6 to 20m. The antenna is only 2.9m long, the max. width is 7m and the weight only 19 kg. This is ideal for terraced house or other situation where very short antenna elements must be fitted into the available space. On 17 and 20m the UB-20MX works as a 2 element 'Moxon' antenna, on 6 to 15m as a fullsize 3 element beam. The Moxon construction still yields a respectable gain of 5.8 dBi with an excellent fron/back ratio. On the other bands this antenna is performing nearly like a traditonal 3 element beam.

2 elementi 6-40m Yagi

 

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.

UB-40MX

 

his antenna model is working as a fullsize 3 element Yagi on 10 to 30m, and as a 2 element fullsize Moxon beam on 40m. This is the first Ultrabeam antenna which uses the Moxon system to reduce space requirements without giving up too much performance. Despite the size reduction by about 30% this antenna has a performance comparable to a traditional two element beam for the 40m band. There is no other Yagi design with the size of a UB-40MX which would result in comparable gain and front/back parameters. The UB-40MX was developed for radio amateurs who dreamed of a 2 element beam antenna for 40m, but where a fullsize antenna was too large - up until now.

UB-50

 

 

The UB-50 is a very special antenna model in the Ultrabeam range, it is a compact beam whichcovers the amateur radio bands from 6 to 40m. This antenna works as a 3 element fullsize beam on 6 to 20m. When working on 30 and 40m the two elements in front are retracted, the rear element becomes the radiator, a rotary dipole. To accomodate the length of a full size dipole for these frequencies the copper band is turned in parallel to the boom. The result is a good SWR and high efficiency nearly identical to a linear fullsize dipole. With the folded element the rotating radius is only 5.6m! The element holders of the UB-50 are reinforced to carry the added weight on the elements.

UB6-40 3 elementi

 

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.

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.
