It's works fine for me. The thing is this first one and only one I ever used, so I cannot compare with the other one. It's because of much less expensive than RigExpert or MFJ's antenna analyzer, many new ham like me using this unit. You can find many info
at YouTube. If you want to see this, I can bring it to Field day. </div>

<span title="">Thank you</span> for your report and summary. I enjoyed it as well. I planned to make a home drew antenna for 6M. But unfortunately, Glassfiber fishing rod I planned to use as pole did not come on time, so I just use paracord and speaker wire
and make kind of 1 λ loop antenna. I attach a photo of antenna how I set up. I set up this antenna on my deck which is only 9 feet from ground. It's very simple but the antenna works just fine and able to QSO to one of west coast station with FT8. I never
work other than FT8 yet on 6M, so I will try other mode as well on September!<br>
