MFJ-1798 Vertical Antenna Instructions
10
In the following steps you will refer to figure 2.
Locate the following parts:
One 72" long 1-3/8" tubing (A)
One 72" long 1-1/4" tubing (A)
One 50" long 1-1/8" tubing (A)
Three 1/4-20 bolts (B1)
Three 1/4-20 nuts (B3)
Three 1/4" split washers (B4)
Three hose clamps (D)
You will use a 1/4" bolt with a lock washer under the 1/4" nut to secure
the tubing sections together. These bolts are only used to "pin" the tubing
in place.
DO NOT OVER TIGHTEN THE NUTS, doing so will flatten the tubing and
actually weaken the structure.
A hose clamp provides additional support. Be sure to properly
snug the hardware after each step.
The antenna can be laid on the ground during this stage
of assembly.
