Verified Purchase

Best vertical I have ever used on 10m and i have tried a lot of them. This is a close copy of the Avanti and they had a great design with the original sigma4. I would advise everyone to guy this antenna about half way up with nylon rope because it does sway a lot in any bit of wind.
