[TowerTalk] Force12 rivets

[Chet]

F-12 antennas are pre drilled at the factory. The instructions with mine say
if there are 3 holes, use 3 rivets and insert all 3 rivets in the holes and
don't pull any of them until you know all 3 line up. If they don't line up
you probably have that particular element reversed.

On some of the driven elements they drill a 4th hole in case you need to
adjust the SWR and on these elements only 3 of the 4 will line up. My
instructions didn't say anything about a 2 rivet rule. 

If you still have 2 out of 3 rivets,insert a new one. Not sure what kind of
failure you had. Did the problematic rivet fall out, did it get pulled all
the way through? Just put a new one in.

I believe that the rule is:

put two rivets at each location .. perpendicular to each other.

Someone told me that in the past.
