1 30 Meter Add-On Kit for the DXE-8040VA-1 Vertical Antenna DXE AOK DXE AOK-INS Revision 0d DX Engineering Southeast Ave. - Tallmadge, OH Phone: (800) Tech Support and International: (330) Fax: (330) DXEngineering@DXEngineering.com

2 The DX Engineering DXE AOK kit adds 30 meter coverage to the DX Engineering 80/40 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.

5 2. To install the four 3/4" carriage bolts into the 30 Meter AOK insulated bracket, use a flat washer and hex nut. Tighten the nut until the carriage bolt is fully seated on the insulator. Once fully seated, remove the hex head nut and washer. Install all four carriage bolts from the same side on the insulator as shown in Figure 2. Figure 2 3. Install the 30 Meter AOK insulated bracket onto the stainless steel laser cut 30 Meter AOK mounting arm using two flat washers, split washers and hex nuts as shown in Figure 3. Figure 3 4. Install the 30 Meter AOK Hot Rodz Bracket to the 30 Meter AOK insulated bracket as shown in Figure 4 using two flat washers, split washers and hex nuts. Figure 4 5. Install the black plastic end caps on the end of the 12" stainless steel Hot Rodz as shown in Figure 5. Figure 5-5 -

6 6. Install one 3/4" carriage bolt into the Hot Rodz bracket as shown in Figure 6 using one fender washer, one split washer and one wing nut. Do not tighten. Figure 6 7. Install the 12" Hot Rodz into the Hot Rodz bracket by loosening the wing nut, sliding the Hot Rodz in place in the grooved areas. As shown in Figure 7, adjust the Hot Rodz so you have each one extending approximately eight inches on either side. Tighten the wing nut. Do not over tighten. During the tuning, the Hot Rodz will be adjusted equally either inward or outward. Figure 7 8. Install the two 2.25" studded band clamps to the stainless steel laser cut 30 Meter AOK mounting arm as shown in Figure 8. Figure 8-6 -

7 Middle Assembly 1. The Middle assembly uses the following parts. Refer to Figure 1 for an exploded view. Quantity Middle Assembly Parts Description 1 Stainless Steel Laser Cut 30 Meter AOK Mounting Arm 1 31 Meter AOK Insulated Bracket # " Studded Element Clamp w/ Stainless Steel Hardware 2 # x 3/4" Stainless Steel Carriage Bolt 2 # 10 Stainless Steel Flat Washer 2 # 10 Stainless Steel Split Washer 2 # Stainless Steel Hex Nut Middle Assembly Parts 2. To install the two 3/4" carriage bolts into the 30 Meter AOK insulated bracket, use a flat washer and hex nut. Tighten the nut until the carriage bolt is fully seated on the insulator. Once fully seated, remove the hex head nut and washer. Install both carriage bolts from the same side on the insulator as shown in Figure 9. Figure 9-7 -

Figure Install the two 2.5" studded band clamps to the stainless steel laser cut 30 Meter AOK mounting arm as shown in Figure 11. (Note - This bracket is mounted to the studded band clamps differently than the upper and lower brackets). Figure

9 Lower Assembly 1. The Lower assembly uses the following parts. Refer to Figure 1 for an exploded view. Quantity Description 1 Stainless Steel Laser Cut 30 Meter AOK Mounting Arm 3 End Insulator - Polyamide Wire/rope connection (US Patent No. D534905) 1 Flex-Weave 30 Meter Wire Assembly, " with Soldered Ring Terminals 1 Wire Assembly, 23.50" Black PVC Insulated with #10 and 1/4" Soldered Ring Terminals " Studded Element Clamp w/ Stainless Steel Hardware 1 Stainless Steel Spring, 1.75" 2 # x 3/4" Stainless Steel Carriage Bolt 2 # x 1" Stainless Steel Carriage Bolt 3 # x 5/8" Stainless Steel Hex Bolt 8 # 10 Stainless Steel Flat Washer 7 # 10 Stainless Steel Split Washer 1 # 10 Stainless Steel External Star Washer 6 # Stainless Steel Hex Nut 2 # Stainless Steel Nyloc Hex Nut Lower Assembly Parts 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. Figure

10 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 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. Figure

11 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. Figure 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. Figure

12 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 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

13 3. Lower the antenna (use a support so the antenna is not laying on the ground) and loosely install the middle assembly 12-1/2" above the junction of the 2.75" and 2.5" elements as shown in Figure 18. Figure Loosely install the upper assembly 10-1/2" below the junction of the 2.25" and 2" elements as shown in Figure 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 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 Flex- Weave wire running between the lower and upper assemblies is snug, but not so tight that it puts strain on the antenna element. 6. Once positioned properly, tighten the middle and upper assembly element clamps in place

14 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. Manual Updates Every effort is made to supply the latest manual revision with each product.
