I’m told the 430 does the same and I would expect the 650 to as well

Thanks for this reference, I learned something. No wonder the database updates are so expensive - they must include mag declination data for all the vor’s, too. Maybe I should have guessed this - I’m pretty sure that de-commissioned VORs disappear from the gps database.
Have you actually pulled the wingtip and looked at the antenna? I’ve seen everything wrong that you can imagine: ground leg a foot away from the end rib, radiating leg against the rib with the ground leg further out(!). I’ve even seen one builder who thought he could tie two Archers (one from each wingtip) together (bad idea).
