This technical note describes the procedure for setting up a multi-turn loop using a 20 foot (6 meter) fiberglass, telescoping pole and the SGC STEALTH Kit. These instructions can easily be adapted to other available poles simply by adjusting the dimensions. These instructions are also available for download as a PDF file (approximately 1.6 MB).
1. Equipment Needed
1 20 foot (6 meter) fiberglass telescoping pole
1 SGC STEALTH Kit or a Smartuner™ and 80 feet of flexible wire
1 tripod or support system for the pole
Scissors or a knife
2. Setting up the Antenna
2.1 Remove the top 2 sections of the pole.
Pull the bottom cap from the pole and remove the two sections in the center. The bottom two sections are inside the innermost section when seen from the bottom. The total length of these sections is 74 inches (188 cm).
2.2 Secure the top two pieces as a cross bar 37 inches (94 cm) below the top.
Use two tie wraps wound around the pole and the cross-piece in an X pattern. Pull these tight using the pliers for leverage.
2.3 Put tie wraps at the top of the pole.
Put two tie wraps together in a figure 8 pattern. (Figure 1) Draw one of the tie wraps tightly around the very top of the pole. (Figure 2)Tighten it on the pole with the pliers.
2.4 Put tie wraps at the ends of the cross piece in a figure 8 pattern and draw one of them tightly around each end of the cross-piece. Tighten them with the pliers.
2.5 Put tie wraps approximately 37 inches (94 cm) below the cross bar in a figure 8 pattern and draw one of them tightly around the pole using the pliers.
2.6 Find the exact center of the 80 foot (24 meter) stealth wire and mark it. Use a piece of Duct tape to mark the center of the wire.
2.7 Put the stealth wire through the bottom tie wrap until the center is at the tie wrap.
2.8. Run the stealth wire around the loop, through the tie wraps from both sides, ending with the remainder of the wires at the ends of the cross piece.
Each side of the wire should go completely around the loop 3 times. On the last loop, take the wire from the ends of the cross-piece. It helps to lay out the antenna on the ground while doing this.
2.9 Secure the Smartuner™ to the pole just below the bottom tie wrap. Use Two (2) tie wraps on the top and two tie wraps on the bottom to secure the Smartuner to the pole. The tuner should be secured in a vertical position, approximately 5 feet (1.5 meters) off the ground. Holes in the base plate (SG-231 & SG-237) are used to run tie wraps through to secure it to the pole.
2.10 Run the ends of the antenna wire to the Smartuner output lugs.
One wire connects to the RF Hot lug and the other to the RF GND lug.
2.11 Erect the pole and secure it in place.
Depending on the circumstances, the pole can be erected in a number of ways. Here it is set up with a vehicle as the major support.
When using this antenna indoors as part of an exhibition, the filled water container will support the bottom of the antenna and a table can be used to provide lateral support. Use Duct tape to secure the pole at the base to the plastic water container. The duct tape should be wound tightly around the pole, the water container, and the legs of the table to provide a firm base of support. Then, lay a line of duct tape across the table and around the pole and then back across the table to hold the antenna firmly against the table. Repeat this several times for lateral support. Once the antenna pole is firmly supported, a table cloth may be used to cover the tape to hide it.
2.12 Connect RF and 12VDC power to the Smartuner. Connect power and RF normally and you are ready to operate.
