Each Command Tiger had a tall "mast" antenna, made of three segments that were kept inside the tank. Two holders for this antenna were fixed to the right-hand hull side.
We are looking downwards at a Tiger hull side. There is a folding clamp for the mast antenna at (2), and a cup at (1) that the antenna will stand in.
Takom provide these parts, but there is an error in their instruction sheet. They tell you to affix the cup facing outwards. Of course it should be facing upwards.
