About this detail of the Tiger
The Tiger carried spare antennae, of length 1.4m or 2m, in a long metal tube. The tube had wide section at one end, with a lid. The tube was welded to the top rear corner of the hull.
The instructions of the Rye Field Model "Tunisian Tiger 1" tell you to attach the antenna tube as shown here; the wide end is to the front, and the back of the tube is some distance from the back of the hull.
The instructions of the "Eastern Front Tiger" are the same. They show the tube attached like this.
But in fact, that position was first used when S-mine launchers were added to the Tiger. Before the launchers were added, the tube was the other way around. Its wide portion extended beyond the rear of the hull.
