Note: JTL-12555 Jet-Lube SS-30 Anti-Seize is recommended to be used on all clamps, bolts and
stainless steel threaded hardware to prevent galling and to ensure proper tightening.
Basic Assembly
Assembling the Center-T Support
This initial assembly is common to all models.
Holding the Center-T, insert a 3/4” Carriage Bolt through the hole shown in Figure 1. The head of
the carriage bolt will be on the same side as the “DXENGINEERING.COM”. This is done so the
element wires (dipole legs) will be routed though the wire restraining holes correctly.
Figure 1 - Carriage Bolt Installation
Holding the carriage bolt in place, turn the Center-T over and install a flat washer, hand tighten the
10-24 hex nut in place. Using a 3/8” wrench tighten the hex nut. As you tighten the nut, the
carriage bolt will draw itself into the support. Tighten the nut until the carriage bolt head is flush to
the support as shown in Figure 2.
