what is wrong with the antenna tube at the HL-Tiger?
Well, nothing.
There are just two of them instead of one.
So you have to remove one.
To store the Antenna when not in use or to store a spare one, the Tiger has antenna storage like a long tube installed.
It is that long thin thing at the back of the hull.
There are two of them, one left and one right in driving direction.
The left one has to be removed.


Cut it off carefully and grind the leftovers.
That´s it.
