Select the DX-88 base assembly and assemble
as shown in Figure 1.
80/40 METER ASSEMBLY
Capacitor Assembly
Construct the two 45" capacitors for the 80/40
meter assembly. Select a 1" x 45" tube (Item
3), 7/16" x 48" tube (Item 1), 3 spacers (Item
35), 1 rain cap (Item 36), and 1 caplug (Item
34) for each capacitor assembly. Refer to
Figure 2.
Push the spacers onto the 7/16" tube and adjust
so that the top spacer is approximately 20
inches from the top end of the tube, the bottom
spacer is near the bottom end of the tube and
the remaining spacer is half-way between the
other two. Push the rain cap onto the top of this
tube and then slide this assembly into the 1" x
45" tube. Seat the rain cap over the 1 inch tube.
Repeat this instruction for the other capacitor.
DO NOT place the caplug on the 7/16" tube at
this time.

Loosely assemble two pairs of 11/8" x 1"
clamps and two pairs of 1 1/8" x 7/16" clamps
as shown in Details B and C of Figure 2.
Select the 80/40 meter coil assembly (Item 14)
and attach the capacitors to the coil assembly
using the clamps as shown in Figure 2. Dimen-
sions A and B will be set later on in the
instructions.
NOTE: All clamps should be placed flush with
the coil form edge and touching each other.
The rain caps should be pushed completely on
each 1" tube, and should be flush with the
11/8" x 7/16" clamp. Tighten the hardware on
these four pairs of clamps. Place the caplug on
the top end of each 7/16" tube.
