The antennas stay basically rigid and straight up when moving as well.

To replicate them, I prefer 0.020 plastic rod over stretched sprue. Also, the actual antennas are about 8' long; 2 3/4 inches in 1/35.
Also, I can't see them, but don't forget the tail lights as well. Only the left upper oval should be red. The slits on the bottom left and both on the right should be gloss black.
M60, but same on an M48A3.
