But of course I was thinking of the exceptions. I use an X-9 on a 70 ft
tower which I shunt feed. I rarely have arcing problems unless something
goes out of whack. This occasionally happens when we get some winds that
blows my shunt wire around or gets my feed lines swinging in the breeze.
Fortunately my Acom shunts down quickly and does send the arc fault msg. I
use a Gamma match but find I need better than a 5K vacuum var. I measure the
capacitive value in the order of 300pfs.
