I have had to send my omni vi plus upgraded to option 3 back to TT 3 times
for no output....replaced the finals and drivers twice and the drivers a
third time. I now suspect the same static issues. It is working fb now
though...
I seem to have the best luck running a link coupled transmatch to feed both
my omni 7 and omni 6.
Feedline has static discharge units...a pair of 100k ohm resistors to
ground. I run a horizontal loop fed with lengths of 600 ohm homebrew ladder
line plus 400 ohm windowed line running from outside the house to the shack.
