WARNING: DO NOT INSTALL THE STEALTH BAZOOKA WHERE ANY PART OF THE FLAGPOLE CAN COME INTO CONTACT WITH OVERHEAD POWER LINES DURING INSTALLATION OR IN THE COURSE OF NORMAL FLEXING AFTER INSTALLATION FOR SUCH CONTACT CAN RESULT IN DAMAGE TO PROPERTY, BODILY INJURY OR EVEN DEATH.

NOTE: PLEASE CONSULT THE A.R.R.L HANDBOOK FOR ADDITIONAL SAFETY PROCEDURES WHEN WORKING WITH ANTENNAS AND ASSOCIATED ELECTRICAL EQUIPMENT.

NOTE: IT IS RECOMMENDED TO READ ALL INSTRUCTIONS THOROUGHLY BEFORE PROCEEDING TO ASSEMBLY.

NOTE: FIRST SURVEY YOUR LOCATION TO SELECT THE BEST SITE FOR THE STEALTH BAZOOKA FLAGPOLE ANTENNA.

IT IS RECOMMENDED THAT YOU SELECT A LOCATION AWAY FROM OBJECTS WHERE PERFORMANCE MAY BE DEGRADED SUCH AS A HOUSE WITH ALUMINUM SIDING OR METAL FENCE.

TAKE INTO CONSIDERATION THAT THE STEALTH BAZOOKA ANTENNA WILL REQUIRE A GROUND RADIAL SYSTEM EXTENDING OUT FROM THE ANTENNA 16 FEET IN ALL DIRECTIONS.

REQUIRED TOOLS

Flat blade screwdriver, Philips blade screwdriver and pliers. A 3/8 inch and 7/16 inch open-end wrench nut driver.

UNPACKING

CAREFULLY REMOVE THE THREE (3) PLASTIC WRAPPING MATERIAL BANDS AROUND THE FOUR (4) PVC PIPES.

NOTE: DO NOT ATTEMPT TO PULL WIRE RADIATING ELEMENT RUNNING BETWEEN THE TWO (2) PVC PIPES.

THE RADIATING ELEMENT IS LOOSELY FED THROUGH THE SIX (6) FOOT MIDDLE PVC SECTION AND THROUGH THE SIX (6) FOOT TOP PVC SECTION DURING SHIPMENT.

MOUNTING / SETTING TUBE INSTALLATION

1. Prepare a hole in the ground 12 inches in diameter and 47 inches deep.

2. Place the four (4) foot PVC Ground Setting Tube into the hole allowing approximately 1 to 2 inches to extend above ground level.
NOTE: ENSURE FLAG POLE BASE ASSEMBLY MOUNTING HOLE IS SLIGHTLY AVOVE GROUND LEVEL.

3. Fill the bottom of the hole with 4 inches of loose gravel.

4. Next fill the hole with 12 inches of sand.

5. Using a level ensure the 4 foot PVC Setting Section is perfectly level (Straight Vertically).

6. Plumb Setting tube and brace so that it will not move during the pouring of the concrete.

7. Fill the hole half way with concrete.
NOTE: Recheck the tube level. Make adjustments as required.

8. Fill the remaining portion of the hole with concrete to within 2 inches of ground level.
See Installation Detail figure below.

9. Again recheck the level of the mounting tube. Make any final adjustments at this time.
NOTE: BE SURE THE GROUND SETTING TUBE IS PERFECTLY LEVEL (STRAIGHT VERTICAL) AT THIS TIME. FAILURE TO ENSURE A LEVEL MOUNTING TUBE WILL RESULT IN THE FLAGPOLE NOT BEING STRAIGHT.

10. Once concrete has hardened (approx. 48 hours) fill hole with top soil.
DO NOT INSTALL FLAG POLE BEFORE 48 HOURS.

FLAGPOLE MOUNTING

1. Install a 6 foot ground rod as close to the mounting tube as possible.

2. Drive the ground rod into the ground using a heavy metal hammer so that only 1 to 2 inches extends above the ground level.

3. Place Flag Pole into ground mounting tube. Insert #10-32 x 3.000 inch screw with #10 Plastic Screw Cover Washer through the top end of the mounting tube.

4. Install flat washer and #10-32 Hex Nut with Teflon insert to the #10-32 x 3.000 inch screw protruding through the opposite side of the PVC mounting tube and tighten securely.

5. Connect the ground radial assembly to the #10-32 antenna GROUND SCREW located directly below the coax feed point connector. (See Figure 1)
NOTE: Refer to Ground Radial Section for proper placement.

6. Connect a ground wire (#10 gauge or larger) to the ground rod.

7. Connect the other end of the ground wire coming from the ground rod to the antenna GROUND SCREW. (See figure 1)

8. Secure both the ground rod wire and the ground radial assembly to the GROUND SCREW with #10-32 hex nuts.
NOTE: A good ground connection is extremely important to achieve low VSWR and proper antenna performance.

9. Connect a 50 ohm coax feed line (RG-58, RG-8 or RG-213) to the recessed SO-239 connector located at the base of the flag pole.
NOTE: The coax connector must be tight to ensure proper antenna performance and low VSWR.

CHECKOUT AND ADJUSTMENT

1. The STEALTH BAZOOKA is pre-tuned from the factory and should produce relatively low VSWR readings over the entire 17 and 20 meter bands and 950 KHz of the 10 meter band.

2. For measurement checks a simple VSWR indicator may be used with a minimum of power for accurate readings. An analyzer may also be used for this test. NO MORE THAN 10 WATTS IS RECOMMENDED TO INITIALLY CHECK THE VSWR.

3. Determine the frequency at which VSWR is the lowest on 10 and 17 meters.
NOTE: Factory settings should produce resonance at 18.1 and 28.3 MHz.

However different ground conditions and antenna location can result in higher VSWR readings. Some adjustments may be required.

GROUND RADIAL PLACEMENT

1. Ensure GROUND RADIAL KIT is connected and tightened securely to the ground terminal of the base tube assembly.

2. Fan out radials as shown in figure 9.

3. Make sure radials are equally spaced as shown below in figure 9.
NOTE: Do not leave radial wires on the ground. It is recommended to bury the wires to prevent damage to the radial kit from pedestrians and lawnmowers.

4. Split the earth 1 to 3 inches with a square shovel or similar tool to provide a straight line along the path of each radial wire.

5. Press ALL radial wires into the split earth being careful not to cut or damage the wire.

6. Always keep radials in a straight line. Do not bend.
NOTE: ADDITIONAL RADIALS CAN BE ADDED IF GROUND CONDUCTIVITY IS POOR.

Figure 9

This is only a representative layout of the ground radials.

Variations of figure 9 will still provide good performance.
