Assembly of Band-Specific Antennas
At least one of the band-specific assemblies must be used before the Garden Antenna is
functional. All needed hardware is included with each assembly. Both the 72 inch and the 24
inch masts (96" total) along with a threaded coupler are included in the Base Assembly.
The
DXE-GAHR-1P
kit is for 10-20M, the
DXE-GA30M-1P
kit is for 30M and the
DXE-GA40M-1P
kit is for 40M.

Assembly of DXE-GAHR-1P 10-20m Kit
This kit includes a custom Hot Rodz mounting hub and six 12", 24" and 36" Hot Rodz. The
threaded to smooth adapter is used to mount the hub to the top of the mast. Protective rubber tips
for the end of the Hot Rodz and an Allen wrench used for the setscrews in the hub are also
included. A radial system is recommended for best performance.
The 12" Rodz are used for 10-15m, the 24" Rodz are used for 17m, and the 36" Rodz are used
for 20M operation as indicated by the table in
Figure 6
.
Install the threaded to smooth adapter to the top of the appropriate mast length, depending on the
desired operating band.

The 10-20m antenna should resonate at close to the following frequencies using the adjustments
in
Figure 6
for the mast and Hot Rodz. The antenna features full band coverage with no tuning
and an SWR of 1.5:1 or less.
10m – 29.160 MHz
12m – 24.960 MHz
15m – 21.150 MHz
17m – 18.125 MHz
20m – 14.160 MHz
Once the desired resonance is achieved, use the base matching coil to reduce the SWR by
compressing or expanding the wire turns on the coil form.
