Purpose: I'm a ham and use a tripod to attach a Yagi antenna in back mounting (length 1m) in the attic and field day activities. Pros: adequate stability, relatively wertig in the price range, fast assembly and disassembly, rotate, easy Conts: wall diameter too thin for aluminum: when tightening the mounting clamp the pipe is gradually deforms.
Solution: I have the two plugs in the upper tube removed and a steel pipe is pushed through both aluminum tubes. So it does the job and the total length is now about two meters. Without optimization measure I give two stars, with it's four. Power or an average of 3 stars.
