Dave,
The entire length of the element is determined by length D on those elements
which in your case is going to be 18". Dimensions A, B, and C determine the
element end/capacitor assembly dimensions. Length D determines how far the
element end/capacitor assembly nests inside the 72"x1" tube and determines the
overall length.
I have rebuilt 3 of them and currently have two in the air and one on the
ground plus a bunch of spare elements from one that collapsed under ice but not
sure if any of the 72" pieces survived in that pile.
There has always been some question as to where you measure from. If I
remember right you measure from the edges of the straps. Soooo:
Dimension A would be from boom side edge of the middle shorting strap to the
element tip.
Dimension B would be from the boom side edge of the middle shorting strap to
the outer edge of the outer shorting strap.
Dimension C would be from the outer edge of the inner capacitor strap to the
outer edge of the inner jumper strap that loops over the element.
Dimension D would be from the end of the swaged 72" x 1" tube to the outer edge
of the inner strap.
Total length of the element would be from the end at the boom to the tip of the
longest element. That would be 72" + 18" + 51.5" + 1" (length of the capacitor
caps back to back) or 142.5"

Hello gang,
I am finally getting some help and want to repair my 34XA reflector. The 1" by
72" that goes to the boom mount bent on me a few years ago. It finally broke
off ad hopefully I will crank the tower down to roof level where the entire
reflector can be reached. M2 sent me a KT-36XA piece and I know I have to drill
and extra hole in the end so it can be mounted. I went to the 1985
documentation and need some help.
I need to know the entire length of the element half plus the length of the 1"
piece from the center to the hose clamp. It looks like the older piece may not
be 72" to the clamp. The Old piece has a short swaged portion and a long cut
out rib to make the hose clamp tight.
I will be able to pull the other half element off to compare but now it is 75
feet in the air.
I last replaced parts to match the latest update in 2008. From the spacer
Length C is 27 and 3/4" and length is 61 and 1/2" to the element tip.
Any ideas (wish I could have found a older 1 x 72" piece).
