Maybe worth looking into Mosley mini beams if weight or wind load an issue. I installed one last year. I have enjoyed the results but antennas can turn into a religious argument. I have limited backyard space so I needed to compromise. Mine is on top of a 33' telescoping aluminum mast attached to the side of the house. Rotator at base. The 4 element beam (3 elements on 10-15-20 and dipole for 12 and 17) weighs less than 16 lbs on 6 foot boom. I liked the idea of 5 band coverage. It's performs far better than my R7 but have not compared it to a hex beam. I have heard good things about hex beams but was bit concerned about potential maintenance issues. I do not run it on high power. So if you are QRO I would not recommend it. Just my 2 cents. Al K2AL Sent from my iPhone
