Something I have wondered for a while ... was there any design logic in WWII German tanks having their antennas mounted on the hull? Presumably, this would prevent the turret from fully rotating when engaging a target from the rear. Of course, certain tanks (Pz.II, Pz.III and Pz.IV) had antennas that could be folded down, but not so with later tanks such as the Pz.V and Pz.VI.

The later model flexible rubber antenna base allowed the antenna to bend in any direction.

rotating barrels also were fitted with a non-ferrous guard to push over the antennae (which were on flexible) bases. That was their clear and simple design logic -- there was no inability to fully rotate the turrets 360°

Check the frame under the barrel. It is not there to protect the gun barrel .....

There is actually two problems with antenna location.
1. Antenna on the hull with a short cable to the radio located by the radio operator/ hull machine gunner sitting under the front right hatch: Can get in the way of the turret but most of the fighting usually happened somewhere in the frontal arc. Having your side or rear towards the enemy is usually a bad idea.

2. Antenna on the turret with a longer cable path to the radio with the additional complication of having to use some kind of connection that can rotate and rotate and rotate without giving a bad connection between the radio and the antenna. This connection must also be in the center of the turrets rotation axle so the cable must go around the breach of the gun.
Another option is to use a slip ring connection but then you have complicated the bearings and rotation mechanism of the turret with the antenna connection. The slip ring surface could also be underneath the hull roof, under the turret race. This will take up a lot of space needed for other purposes and create maintenance issues.

Solutions to problems above:
1. Foldable antenna and something insulated which could push it over.
2. Mount the antenna on the hull or move the radio operator to the turret.

There are plenty of situations when the designers need to protect the rest of the vehicle/ship/aircraft from being damaged by its own weapons.
