It looks as if you approached the trooper from the rear and caught up to him. If so, then the rear antenna was appropriate.
The officer's added commentary does not change the underlying offense. You can go to court and argue your position, but as you have been told the officer will not be there unless you subpoena him. And, as previously explained by others, that may not be in your best interest. If the judge is decent at his job, the supposition made by the officer will have no real effect on the outcome as it was not relevant to the offense.
