Liridice Also: I used the original 1310mm pull handle, but it didn't include the angle value. I then tried using a 1400mm pull handle, and after several tests, I found that at a 20° angle, it was almost resonant. This is based on experimentation; simulation doesn't produce this result.
Furthermore, my antenna mounting plate also has spacing, so I didn't complete the job properly, but the results are still acceptable.
