[TowerTalk] 75/80 vertical

okay tower talk fans -- I am new at this, but considering a similar project.

1.	Rather than run a a second, separate wire all the way  parallel to 
the tower, which would, I believe, if I learned my electrical theory 
correctly, have a different resistance than the tower itself, more or 
less, I don't know -- but still it seems that some knowledge of parallel 
circuits and parallel resisters should be applied before you do that. 
It seems to me the current will go the line of least resistance. 
Either the Tower or the wire would be more or less redundant or ignored.

2.	I would think, therefore, based on the above, it would be better to 
use short stainless steel jumpers to bridge the tower section linkages. 
  That would make sure the connection is complete, and make sure that 
power, itself, is doing the conducting.

3.	Could one use his multimeter to check for continuity and good 
conductivity before messing with any of this?  I won a multimeter at the 
Dayton Hamvention last year, and I'm still learning how to use it, but 
it seems like one of those could test for good conductivity.
