I have a pair in a stack and they are wonderful ! Leave that bracket alone -
you'll be fine.

Recently acquired a used Force 12 XR-5 antenna from a friend. The antenna is
a few years old and was from the original Force 12 company. I contacted the
New Force 12 company and got a new dimension sheet which is called V.007.
This version had slightly different element dimensions on 4 elements as
compared to the antenna I have which is V.006. Mark at Texas Antennas (new
Force 12) said they haven?t had any problems with the current dimensions. I
started to change the element lengths. After completing 2 elements, I
noticed that the new dimension sheet also showed that one of the element
brackets was moved ¾?closer  to its next bracket, from 10.5? to 9.75?.

I do recall that some early users said that there were some problems on 15 M
with resonance/SWR. Could this have been the remedy?

I?d like to go with the new dimensions, but am concerned that I?d need to
move that one bracket. To do that I?d need to get the appropriate rivets and
find out the size of drill to redrill the holes.

Wondering if anyone has had experience with what I?m saying? Would
appreciate any comments or experiences.
