Instructions

Model HF6V-X

PLEASE READ ALL INSTRUCTIONS THOROUGHLY BEFORE PROCEEDING TO ASSEMBLY. 
DURING ASSEMBLY AND INSTALLATION TAKE EXTREME CARE TO AVOID CONTACTING
POWER LINES WITH ANY PART OF THE ANTENNA OR OTHER CONDUCTORS.

DO NOT INSTALL THE ANTENNA IN ANY PLACE WHERE ANY PART OF IT CAN COME INTO
CONTACT WITH POWER LINES IN THE EVENT OF STRUCTURAL FAILURE OF ANY PART OF
THE INSTALLATION OR IN THE COURSE OF NORMAL FLEXING AFTER INSTALLATION,
FOR SUCH CONTACT CAN RESULT IN DAMAGE TO PROPERTY, BODILY INJURY OR
DEATH!

IN NO CASE SHOULD THE ANTENNA BE INSTALLED IN ANY PLACE WHERE STRUCTURAL
FAILURE OF ANY PART OF THE ANTENNA OR ITS SUPPORTING SYSTEM CAN ENDANGER
PERSONS OR PROPERTY.

CAUTION!  A GROUNDED ANTENNA WILL BE AT DC GROUND POTENTIAL!  TO AVOID
DANGER OF SHOCK CONNECT ALL STATION EQUIPMENT TO A GOOD EARTH GROUND.  IT
IS ALSO RECOMMENDED THAT ALL STATION EQUIPMENT BE DISCONNECTED FROM THE
POWER MAINS BEFORE CONNECTING THE FEEDLINE TO THE ANTENNA.  PLEASE
CONSULT THE A.R.R.L. HANDBOOK OR OTHER REFERENCE MANUALS FOR ADDITIONAL
SAFETY PROCEDURES WHEN WORKING WITH ELECTRICAL EQUIPMENT.

Tools required for assembly: flat blade screwdriver, pliers and a knife.  A set of nut-drivers will be
useful.

ASSEMBLY

TO ASSEMBLE AN HF9V-X, FOLLOW THESE INSTRUCTIONS, THEN INSTALL THE
A-17-12 AND A6 ADAPTERS.

NOTE: A small packet of anti-seize/anti oxide compound will be found inside mounting post A.  This
compound should be applied lightly to each tubing joint and to the inside of all clamps that must make
good electrical contact with the tubing sections.

Refer to the appropriate drawings and diagrams and proceed as follows:

1. Check to be sure that all parts are present (see parts pictorial page.)

2. Locate tube A w/insulator (A).  This is one of two lengths of 2' x 1 1/8" tubing that has a glass-epoxy

insulating rod attached to it at one end.  Tube a w/insulator (A) can be recognized by the long
machine screw passing through the tube and the insulator.  Do not confuse it with the piece of the
same size and length that has the short machine screw.

3. If the antenna is to be installed at ground level, plant tube A w/insulator (A) in a hole approximately

21" (55cm) deep so that the upper end of the glass-epoxy insulator rod is approximately 5", 12 cm
above ground level.  Pack earth tightly around the mounting post so that it will remain vertical. 
Concrete may be used in areas of high winds for greater strength, in which case the post may be
twisted slightly during setting for easy removal later.  The mounting post tube should be protected
