After about a year of service, I have taken down my beam for 2m and 70cm which was not working as it did. In the near future I want to erect big-wheels instead. According to Wimo literature they have an omni pattern and a single big-wheel has a gain (horizontal) of 3dBD. Spacing between a 70cm big-wheel and a 2m big wheel needs to be 1.5m. This gain is a little down on the beam but needs no rotating. At the moment I think I'll install a single big-wheel for 2m and one for 70cm both fed with low loss coax on a single mast as high as I can. These should suit my operating fine. I monitor beacons and take part in some 2m and 70cm contests from home in a non-intensive way. A couple of big beams would be nice but these would need a rotator.
