Subject: [TowerTalk] F-12  Linear Loading Wire

<Hello TT'ers.

  <I am In the process  of rehabbing   a  Force 12 Delta  240/230  beam antenna.
<In the past I have rebuilt/repaired the original F-12  wires with Aluma-weld 
12GA.
<If my memory serves me there was a thread  in the past because of the flexing  
and hardening  resulting in failure... another  type of wire was substituted ?

<Copper Weld ? Galvanized  fence Wire ?

<Wayne W3EA

##  alumo weld is just aluminum clad steel..which is just as strong as copper 
clad steel, or copper weld.  Those huge curtain arrays you see used for SW HF 
broadcast 
all use alumo weld.    Instead of 14 gauge alumo weld, use something a bit 
bigger, like 12 gauge or even 10 gauge alunmo weld.  I have a 500 ft roll of  
10 gauge alumo weld.
That stuff is indestructible.   You could also replace the LL wires  with 
coils.  I believe F12 or inovate  in the uk offered a coil retrofit  for the 
F12 delta 240 – 230 yagi. 
JK ants could also supply the coils.  But if coils are used, the tips will have 
to be adjustable  to resonate each ele.    Also each of the oem eles will 
require an overhead truss line,
typ made from  .1875  dacron line.
