The radar tower is a neat accessory but that vibrotor is not the best. There should be 4 rubber grommets on the feet which does help but it is still noisy.
This first picture is without the rubber feet, which I magaged to find at York after I took the photo.
The 'real' radar tower at the Reading, PA airport! It's been there for decades. I believe the rectangular piece at the top is relatively new.
