dual band vertical antenna without giving up any existing band coverage.

This kit will operate across the entire 30 meter band at full legal limit with an SWR of 1.5:1 or less
and adds negligible wind loading to the antenna.

No disassembly of the existing antenna is required.

Simply install this kit, check the tuning (if needed, make some minimal tuning adjustments) and
you're on the air with an additional band.

2. Attach two end insulators to the mounting arm. Use one 3/4" carriage bolt and one 5/8" hex
head bolt along with a flat washer, split washer and hex nut for each end insulator as shown in

Figure 12.

3. The black wire (23.5") has two different sized ring terminals. Take the smaller ring terminal end
and loosely weave the wire through the second hole of end insulator as shown in Figure 13.

Figure 13

4. Assemble the last end insulator as shown in Figure 14 using the Flex-Weave (233") wire, the
black wire (#10 ring terminal end) and the stainless steel hardware Note the hex head bolt has a
recessed area the head fits slightly in during assembly. Note, when putting the stainless steel
spring on, use the Nyloc hex nut only tightened as shown in Figure 14. This allows the spring to
move, but not come off.

5. Connect the assembly from Step 4 to the lower assembly as shown in Figure 15. Install the 1"
carriage bolt, flat washer, split washer and hex nut. Then slide the spring in place and use the
Nyloc nut to hold the spring in place as shown.

6. Install the two 3" studded band clamps to the lower assembly as shown in Figure 16. Note the
orientation of the band clamp adjustment screws.

Attaching the 30 meter assemblies to the DXE-8040VA-1 vertical antenna

Before you start installation, measure the low SWR frequencies of your DXE-80/40VA-1 vertical
antenna on each band and record those measurements. This will assure your antenna is working
properly before adding the 30 meter kit and aid in making minor adjustments afterwards, if needed.

The orientation of the 30 meter kit on the DXE-8040VA-1 is important. The positioning of the 30
meter kit must be such that it does not interfere with the tilting of the antenna.

1. The lower 30 meter assembly is installed first while the DXE-8040VA-1 antenna is in the
upright position. The lower mounting bracket is attached to the base section using the stainless
steel studded band clamps as shown in Figure 16. With the clamps open, you can insert them
around the bottom aluminum element. Position the clamps just above the feedpoint as shown
and tighten in place.

Figure 16

2. Connect the black wire to the radial plate as shown in Figure 17. Adjust the black wire length
through the insulator to allow lowering the antenna and not interfering.

Figure 17

- 12 -

3. Lower the antenna (use a support so the antenna is not laying on the ground) and loosely install

Final positioning of the upper bracket should be done so the FLEX-WEAVE™ 30
meter wire is parallel to the DXE-8040VA-1. The spring should have tension to allow it
to keep the 30 meter wire taught when the antenna flexes in the wind.

Ensure the lower, middle and upper assemblies are in line and the 30 meter Flex­Weave wire running between the lower and upper assemblies is snug, but not so tight
that it puts strain on the antenna element.

the middle assembly 12-1/2" above the junction of the 2.75" and 2.5" elements as shown in

Figure 18.

Figure 18

4. Loosely install the upper assembly 10-1/2" below the junction of the 2.25" and 2" elements as
shown in Figure 18.

5. Run the FLEX-WEAVE™ 30 meter wire attached to the lower assembly through the middle
assembly insulator large hole and attach it to the top bracket using the carriage bolt, flat
washers, star washer, split washer and nut as shown in Figure 19.

Figure 19

6. Once positioned properly, tighten the middle and upper assembly element clamps in place.

Tuning

An antenna analyzer is the best way to measure the SWR of the 30 meter assembly. The antenna
measurements should be made at the antenna base using a short (5 or 6 foot) piece of 50Ω coax
between the antenna and the analyzer. If you are too close to the antenna your presence can affect
the tuning, if you are too far, the coax length may act as a radial and resonate.

Raise the DXE-8040VA-1 to the full vertical position. Taking readings close to the antenna also
eliminates the possibility of a long or marginal feedline influencing the tuning or causing erratic
readings.

The 30 meter add-on kit electrically couples to the rest of the vertical but should not have influence
on the tuning of the 80 and 40 meter bands.

Adjustment of the 30 meter add-on kit SWR is done
by slightly loosening the wing nut holding the Hot
Rodz™ and adjusting the length of the Hot Rodz™.

Adjust both Hot Rodz™ equally longer to go lower
in frequency or equally shorter to go higher in
frequency.

Make adjustments in small steps.

Once tuning is complete, firmly tighten the Hot
Rodz™ in place using the wing nut.
