Not true in my case. Before I installed the porcupine my
mast bleed off the charge. A number of years ago I added
the porcupine and my mast/porcupine combo still bleeds off
the charge. In other words, my addition of the porcupine

If you want to minimize the chance of a lightning strike to
your tower do
not place a device on the top with sharp points. A blunt
point rod should be
placed at the top.
The so called lightning preventers or porcupine items do
nothing to abate a
strike. In fact they can increase the chance of a lightning
providing sharp points where early streamers can form. There
is no way to
"bleed off" any energy from a tower as the earth can
re-supply it many times
faster than you can get rid of it.
