Matching Coil and Feedline Assembly
As shown in
Figure 2
, a 3/4 x 2 inch aluminum bracket is used to mount the matching coil and
feedline pigtail. Use the 1/2 inch bolt and star washer to mount the bracket to the brass antenna
mounting block. Place a star washer on one of the coil assembly mounting bolts and insert it
through the bracket. Put on another star washer and attach the red lead from the feed line pigtail,
then a nut and tighten. Install the black lead of the feed line pigtail to the other end of the coil
assembly using another star washer and nut as shown. Connect your coax feedline to the pigtail
using a female to female SO-239 adapter. If you are using a DX Engineering Radial Plate, the
pigtail should connect to the radial plate using a bulkhead adapter such as the
DXE-363-SST
SO-239 bulkhead fitting. (See
Figure 1
)

Mounting the Quick Disconnect
The quick-disconnect fitting shown in
Figure 3
is used to allow quick removal of the antenna if
needed. If the quick disconnect is not needed, the mast can be mounted directly to the brass
block using one of the threaded adapters. To use the quick-disconnect fitting, first disassemble it
by turning the knurled portion while holding the bottom section. Unscrew the short threaded rod
from the bottom section as shown in
Figure 4
. One end of the threaded rod has a 3/16 Allen head
built into it. Screw the rod end with the Allen head back into the bottom quick-disconnect section
until 1/2 of its length is inside (about 1/2 inch).
