Stealth Bazooka
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 20
meter band and 150 KHz of the 40 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 20 and 40 meters. NOTE:
Factory settings should produce resonance at 14.2 and 7.200 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.
