INSTALLATION CONSIDERATIONS
NOTE: DO NOT USE U-BOLTS TO ATTACH TUBE W/INSULATOR (A) TO A MAST, TOWER ETC. U-
BOLTS WILL EVENTUALLY CUT INTO THE TUBING AND WEAKEN THE INSTALLATION. If U-bolts
must be used, place a larger diameter metal tube, such as the MPS Mounting Post Sleeve over tube
w/insulator (A). Similar precautions should be observed when using TV style towers with locking bolts.
Tube w/insulator (A) may be slid into a mast of suitable diameter, preferable up to the insulator. A hole
may be drilled through the mast and tube w/insulator (A) to hold the two together.
INSTALLATION AND ADJUSTMENT
The HF6V/HF9V is sufficiently balanced that it may be manhandled into place over the rod insulator atop
tube (AA) by one person of average height, even in a fairly stiff breeze.
G
1. Wiggle the antenna slightly until the holes in the lower tube can be aligned with the holes in the
rod insulator, insert a screw from the antenna hardware and secure with a lock washer and hex
nut
Hint: disconnect one or more of the clamps and attached wires from the counterpoise if you have to
stand close to the antenna as it's raised or lowered.
G
2. Connect the wire from connector assembly (AH) to the screw securing tube (B) to the insulator
on top of tube (AA). Secure with a lock washer and hex nut.
ADJUSTMENTS/MODIFICATIONS TO THE HF6V/HF9V FOR USE WITH CPK
Refer to CHECKOUT AND ADJUSTMENT found in the HF6V/HF9V instruction manuals. The following
modifications may be useful in adjusting antenna tuning for operation with the CPK.
G
1. The short 75-ohm matching line that is packed with the antenna is not used. Store it away for
possible future use, but remove the PL-258 double-female connector.
G
2. Connect the coil support tube 30 meter L bracket (O1) around the fourth turn of the 40 meter
coil on coil assembly 80/40 meter (C).
G
3. The placement of the 12 meter circuit is not especially critical but it may be found that SWR at
the lower heights (below about seven feet) can be improved by sliding the whole 12 meter unit to
a higher position on the antenna.
G
4. Adjust tube (J) so that 24 in (61 cm) extends from the slotted end of tube (I).
With this setting, SWR will be lowest over the upper end of the 10 meter band. If operation over the
lower 500 kHz of the band is contemplated attach the capacitive hat.
G
5. Using the adjustable compression clamp, attach the capacitance hat 12 in (30.5 cm) from the top
of tube (E) on tube (F).
G
6. Starting 6 in (15.2 cm) from one end of the coax matching line, place ten marks spaced 37-
43/64 in (95.8 cm). Coil the coax, lining up each mark until you have 9-1/2 turns. Using tape or
cable ties, bind the coil in at least four places.
NOTE: The coax coil should not be held in a helical form like the 80 and 40 meter coils are.
