You are running an A99 antenna that has tuning rings on the base of it. You don't trim this kind of antenna; you use the tuning rings! Mark where they are before you begin to adjust them. This way you can go back to the way it was if you need to return to your original adjustments.

Don''t move them too much, and be sure to re-calibrate your SWR meter each time you check it.
That is imperative.

Since you are new or have returned to the hobby, then a little reading would be wise to get your mind around it once again:
