Hub Assembly
The custom machined hub mounts the Hot Rodz and attaches to the top of the antenna mast
using set screws. Use the included Allen wrench to install set screws in all of the threaded holes
in the hub. The threaded holes with close vertical spacing are used to secure the Hot Rodz in the
hub. The two threaded holes spaced further apart are used to secure the hub to the top of the
antenna as seen in
Figure 8
. The longer setscrews are used in these holes.
Figure 8: Set screws
Determine the desired band of operation and select the correct length Hot Rodz from the table in
Figure 6
. Install the black rubber tips on one end and insert the opposite end into the holes of the
hub as shown in
Figure 8
.
The Rodz adjustment dimensions from the table in
Figure 6
are measured from the center of the
hub to one end of the Hot Rodz as shown in
Figure 9
. All the Rodz should be adjusted the same.

As an example, to configure the
DXE-GABU-1P
Base and the
DXE-GAHR-1P
10-20m kit for
10 or 12m operation, use just the 72" mast as indicated in
Figure 6
. Install the 12" Rodz in the
hub and adjust them so there is 6" from the hub centerline to one end of the Rodz as shown in
Figure 9
. Install the hub onto the threaded to smooth adapter at the top of the mast using the two
wider-spaced set screws. For 12m operation, simply re-adjust the Hot Rodz. All that's left to do
is fine-tune the SWR using the base matching coil.
