1. First loosen all of the turnbuckles on the element trusses and apply anti-seize to the threads, this is important so that
you will be able apply tension to the truss later by tightening the turnbuckles to take up slack.
2. The Phillystran may be precut
to 230” for the 70ft element or 115” for the 50ft element.
3. Start at the lower end of the truss where it attaches to the fiberglass extension (near the joint with the telescoping
tube).
4. Slide three wire clips onto the Phillystran and then feed it through the thimble until there is ~8 inches of rope on the
“dead” side. Guide it around the thimble and then back through the wire clips. Pull the rope taught so that it conforms
to the shape of the thimble.
5. Arrange the thimbles ~ 1.5 inches apart as shown and tighten. Tighten the thimbles at least twice waiting at least 15
minutes between tightenings. Generally, if you tighten them in a consistent order, by the time you tighten the last
element you can go back and retighten them all in the same order.
6. Pull the rope to the other attachment point: the 5/16 x
8” turnbuckle at the top of the mast. Make sure to attach to the
larger
5/16” turnbuckle and not the smaller 1/4” turnbuckle.
7. Pull the rope tight and then cut it 12 inches past where it meets the
“eye” of the turnbuckle. This is to give you extra
material.
8. Repeat steps 3-4.
Make sure that you apply tension to the rope in step 3,
any slack left in the line will need to be
taken up by the turnbuckle before it can apply tension to the line. The turnbuckle has 8” of travel so if you leave too
much slack in the line you might not be able to tension the line appropriately.
9. Apply tension to the Phillystran (inner) guy wires by twisting the 5/16 x
8” turnbuckles.
10. Use a level to confirm when the element is leveled.
11. When the elements are level, secure the turnbuckles with the provided locking wire to prevent them from loosening.
12. Install the rubber cap on the loose ends of the phillystran and
then wrap the ends with electrical tape to secure them.
