Regular readers may remember that I was asking about rotators some months back. Well, I have just realised that the place where I intend to fix my 2 inch diameter mast at the new QTH is such that I can rotate it by hand by opening a window about 10 feet from my new operating position. This means, if I so choose, I can erect a small beam for 2m and 70cm, or a combined 2/70cm beam and turn it 360 degrees very quickly using the trusty "Armstrong" method. So, initially I'll erect the V2000 vertical but may well add some small (not too sharp) beams for VHF/UHF contest and tropo work. Turning a beam by hand is quicker than a rotator and allows signals to be peaked by ear.
Anyone have any recommendations for a combined 2m/70cm horizontally polarised beam with around 3-6 elements, ideally fed with a single 50 ohm coax? I have seen combined 2m/70cm HB9CV antennas but think there are other options too.

Does anyone have any experience of this rotator?
