[TowerTalk] F-12 Linear Loading Wire

[Wayne Kline]

John,

 RGR on Linear loading is not the BEST  electrical ( RF) Design....  the Tornado loading coals available   from JK would be the cat's MEOW  but a 48 apiece X  8    and then the new extra aluminum need to strengthen the element ...  I'll  think I am leaning on using  the  9 Ga. copper weld.
This antenna is going up on a 74 ft tower I put up two years ago with two Home Brew  HB 6 element OWA  10 meter stack 75/40  but  it's now going to be a 12/17/30 meter tower wit the two element  40  ( I'll point it S S/E for the Caribbean SA) and use my  other  two element forty on  it's own tower  @ 108 pointed on EU   JA   ZL VK

Years ago I had a homebrew 80m dipole with stainless steel wire rope element
support/loading wires. There were never any mechanical issues however
stainless is a poor conductor compared to aluminum. I am not sure what
effect this had, also linear loading is probably not the best method of
element shortening.

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
?

 Coper Weld ? Galvanized  fence Wire ?
