The long-range radio set of a Befehlstiger could have its range extended by putting its antenna on top of a tall mast. The tank carried a 3-piece steel mast of length 3.75 meters. This could be assembled and attached to the side of the Tiger, which would have to be stationary. On top of the mast, isolated by an insulator, was the radio's standard antenna. A cable connected the antenna to its usual post on the hull roof.
Two small clamps were attached to the right-hand side of the Tiger 1 for holding this mast. They were found on Befehlstigers only.
This profile drawing shows the lower holder, which was a simple metal cup welded to the side wall, and the upper holder, which folded out of the way and had a locking lever. The position of these items on the hull was always the same and can be quickly found by counting the bolts in the side skirts.
The upper holder was welded to the hull roof. When it was deployed, as in this drawing, it was directly over the cup on the hull side. The locking lever caused it to grip the mast.
This holder was on a hinge and was usually folded out of the way to protect it.
The ex-Befehlstiger in Kubinka museum still has a complete set of holders.
