I had the direction indicator pot in the T2X burn up with RF  when using the 
tower as a vertical. The RF current  through the rotator to the capacity hat of 
the 205BA appeared to cause the problem: adding suitable straps between the top 
of the tower and the stub mast, as well bypass  caps in the T2X,  led to no 
recurrence in 20 years.
But this purely anecdotal, of course. I believe it's backed by theory - others 
may disagree.
