The OB8-4M is an extremely effective, compact and innovative Yagi for the classical four bands 40, 20, 15 and 10m. It is the first trapless Yagi for this frequency spectrum in the world with a single 50 Ohm coaxial feed and with two powerful Moxon Rectangles integrated in its design to improve performance. A mechanically brilliant power house without compromise, the next level of antenna performance!

- usage of all advantages of the 2 element loaded Moxon Yagi for 40m, see OB2-40M
|
- on 20m a 2 element full size Moxon allows for outstanding gain and a super radiation pattern with extremely high F/B
|
- 2 fully resonant active elements on 15m are additionally enhanced by the 10m director in front which results in an increase of gain and an optimised radiation
|
- a driver-director combination on 10m already delivers higher gain and F/B ratio figures which are increased close to the values of a 3 element monobander due to additional positive effects of the 15m elements in the rear
